A’ja Wilson against ranked teams for the last 2 seasons PTS PER 40 MINS.FIELD GOAL PERCENTAGEDOUBLE-DOUBLES 2014-1523.147.42 2015-1626.6 points53.1%7 Coates, the 2013-14 SEC Freshman of the Year, leads the nation in field goal percentage and has an SEC-best 12 double-doubles this season. Coates and Wilson are averaging a combined 29.6 points per game, the most by any frontcourt duo in the SEC. Overall, South Carolina is averaging 40.3 points per game in the paint and has outscored its opponents down low in every game this season.Based on their performance, the Wilson-Coates tandem could prove difficult for UConn to defend. Maryland’s Brionna Jones — one of the premier post players in the nation, with skills and stature similar to Wilson and Coates — put up 24 points against the Huskies earlier this season. UConn allowed a season-high 38 points in the paint to the Terrapins and trailed in the third quarter for the only time this season.South Carolina is also aggressive on the offensive glass, averaging 8.6 points per game on put-backs2All tracking data courtesy of Synergy Sports Technology. and grabbing 13.7 offensive rebounds per game. Connecticut is allowing 10.7 offensive rebounds per game but the Huskies’ opposition has failed to capitalize, managing just 3.5 points per game on put-backs.And don’t discount South Carolina’s home-court advantage. The Gamecocks have won 45 consecutive home games, the longest active streak in Division I, and are on track to lead the nation in attendance for the second consecutive season. Notably, South Carolina averages 80.2 points at home, compared to 68.4 points on the road.But will a strong post presence and a favorable crowd be enough to hand Connecticut its first loss in over a year? Probably not. UConn is on pace to lead the nation in both offensive and defensive efficiency for the fourth consecutive season; to have a chance against Connecticut you need to score at least 70 points. Over the last five seasons, UConn is 5-7 when opponents score 70 or more points, compared to 163-3 when holding its opponent to 69 points or fewer.And here’s the bad news for Gamecocks fans: South Carolina is tied for eighth in the nation in offensive efficiency but has been held below 70 points on seven occasions this season, four times against ranked teams.The Gamecocks also struggle on 3-pointers and free throws, which isn’t ideal when you’re trying to run up a big number on the Huskies. South Carolina is shooting 31.4 percent from deep this season, which ranks 150th in Division I. In one of Connecticut’s most tightly contested games this season, Notre Dame shot 65 percent from beyond the arc, making 13 3-pointers. DePaul and South Florida also had early success against Connecticut, making 12 or more 3-pointers and shooting 45 percent or better from beyond the arc.The view is even worse from the foul line, where South Carolina ranks 272nd in the nation with a 65.3 percent free throw percentage. Facing a Connecticut squad that holds opponents to a Division I-low 6.2 free throw attempts per game, the Gamecocks need to convert on any opportunity to put points on the board.Is South Carolina capable of upsetting Connecticut on Monday night? It’s possible, sure. But SC will need either something truly absurd out of Wilson and Coates or a momentary reprieve from its season-long trend of their range extending no farther than the length of their arms. While the rest of the country recovers from its post-Super Bowl hangover, the South Carolina women’s basketball team will attempt to do what only one team has accomplished in the last 35 months: beat Connecticut.The UConn Huskies are in one of the most dominant stretches in college basketball history, winners of 59 straight and 106 of their last 107 games. The South Carolina Gamecocks are having an impressive season of their own, off to a 22-0 start for the second consecutive season. And Monday night’s game between the only undefeated teams in Division I basketball will be the 56th meeting between the AP’s No. 1 and No. 2 women’s college basketball teams. The last such meeting did not turn out so well for the Gamecocks, with No. 2 UConn beating No. 1 South Carolina, 87-62 in Storrs, last season to snap a 22-game win streak.For any hope at a better result this season, the Gamecocks will need something special out of their dynamic duo on the interior, A’ja Wilson and Alaina Coates.Wilson is the reigning SEC Freshman of the Year and top-ranked recruit for the Class of 2014,1According to ESPNW and HoopGurlz rankings. and she has elevated her game in her sophomore season, becoming South Carolina’s go-to player against ranked teams. The 6-foot-5-inch forward has accounted for 25.6 percent of South Carolina’s points and 26.3 percent of its rebounds against Top 25 opponents this season. Wilson had a tendency to disappear in big games last season, but she’s now averaging 26.6 points per 40 minutes against ranked teams and has a double-double in seven of her nine games against Top 25 opponents this season, more than she had all of last season.

DOI:10.1103/PhysRevLett.106.140502AbstractWe describe a method to enhance the sensitivity of precision measurements that takes advantage of the environment of a quantum sensor to amplify the response of the sensor to weak external perturbations. An individual qubit is used to sense the dynamics of surrounding ancillary qubits, which are in turn affected by the external field to be measured. The resulting sensitivity enhancement is determined by the number of ancillas that are coupled strongly to the sensor qubit; it does not depend on the exact values of the coupling strengths and is resilient to many forms of decoherence. The method achieves nearly Heisenberg-limited precision measurement, using a novel class of entangled states. We discuss specific applications to improve clock sensitivity using trapped ions and magnetic sensing based on electronic spins in diamond. The researchers, Garry Goldstein from Harvard University, along with coauthors from Harvard, MIT, Copenhagen University, and the California Institute of Technology, have published their study called “Environment-Assisted Precision Measurement” in a recent issue of Physical Review Letters. In their study, the scientists first describe an idealized case, and then demonstrate that it works in two different cases: quantum clocks with trapped ions and spin-based magnetometry.“We realized that part of the environment can be used to increase sensitivity,” coauthor Paola Cappellaro of MIT told PhysOrg.com. “We found that entangled states, other than the ones usually proposed for metrology (GHZ states, squeezed states) can improve the sensitivity while being more robust to decoherence.”As the scientists explain, a quantum sensor can be constructed with a central spin coupled to a bath of dark spins, which are part of the environment. All of these spins act as qubits, each having a state of 0, 1, or a superposition of both. While the central spin can be controlled and read out, the dark spins can only be collectively controlled and not directly detected. Also, the central spin and the dark spins can be coupled, and this coupling can be effectively turned on and off at will.The central spin can indirectly measure the external field, such as a magnetic field, by sensing the dynamics of the surrounding dark spins, which are in turn affected by the external field. To do this, the researchers first entangled the central spin to the dark spins, and then used this entangled state to sense the external field. As the entangled dark spins evolve, they acquire a phase that depends on the state of the central spin. Then, the researchers could flip the central spin and read out its signal. By reading this signal, the researchers could measure the phase difference between the states of the dark spins, which provides a measurement of the external field.Importantly, the additional phase difference due to the dark spins amplifies the signal of the central spin and allows it to read out a smaller field than before; the smaller the field that a sensor can read out during a given time, the higher its quantum sensitivity. While the signal is enhanced, the background noise stays the same.“Here we assume that part of the environment (the ‘dark spins’) can be controlled, although it cannot be directly measured,” Cappellaro said. “In this scenario, there are two possible strategies: manipulate the environment dark spins to decouple them from the sensor or exploit them by creating an entangled state with the sensor spin. We found that this second strategy is viable and yields better sensitivity.”Overall, the method achieves precision that approaches the Heisenberg limit. This limit results from the Heisenberg uncertainty principle and marks the maximum sensitivity that any measurement can achieve.When comparing this method to another measurement precision procedure based on a spin-echo, the researchers found that the new method has greater sensitivity due to the central spin’s signal amplification. Both methods have about the same coherence times, since, for both methods, decoherence arises from interactions among dark spins, not the rest of the environment.As the simulations demonstrated, the new method could have applications in improving clock sensitivity using trapped ions and magnetic sensing based on electronic spins in diamond. The scientists also predict that this method could be applied more generally to a wide variety of systems.“Extremely sensitive clocks are very important, for example, for global positioning,” Cappellaro said. “Magnetic sensors could find applications in a broad range of areas, from materials science to bio-imaging.” Explore further Creating a pure spin current in graphene Citation: Sensitivity of precision measurements enhanced by the environment (2011, April 27) retrieved 18 August 2019 from https://phys.org/news/2011-04-sensitivity-precision-environment.html This document is subject to copyright.

(PhysOrg.com) — When it comes to quantum measurements, interaction with the environment usually limits sensitivity, since it causes decoherence. But in a new study, scientists have shown that the environment can be advantageous. They have designed a method to increase the sensitivity of quantum precision measurements by using the environment to enhance a quantum sensor’s response to weak perturbations in an external field. A model of a central spin coupled to a spin bath of dark spins, which are part of the environment. By sensing the dynamics of the dark spins, the central spin has a greater sensitivity that allows it to read out smaller external fields, such as magnetic fields. Image credit: G. Goldstein, et al.
