Contextuality Can be Verified with Noncontextual Experiments
Jonathan J. Thio, Wilfred Salmon, Crispin H. W. Barnes +2
We uncover new features of generalized contextuality by connecting it to the Kirkwood-Dirac (KD) quasiprobability distribution. Quantum states can be represented by KD distribution…
Almost no experiments have classical Kirkwood-Dirac representations
Christopher Langrenez, Wilfred Salmon, Stephan De Bièvre +3
A central problem in quantum information is determining quantum-classical boundaries. In the quasiprobability framework, a state is called classical if it is represented by a quasi…
James-Stein Estimation in Quantum Gaussian Sensing
Wilfred Salmon, Sergii Strelchuk, David Arvidsson-Shukur
The James-Stein estimator is a biased estimator -- for a finite number of samples its expected value is not the true mean. The maximum-likelihood estimator (MLE), is unbiased and a…
Fast algorithms for classical specifications of stabiliser states and Clifford gates
Nadish de Silva, Wilfred Salmon, Ming Yin
The stabiliser formalism plays a central role in quantum computing, error correction, and fault tolerance. Conversions between and verifications of different specifications of stab…
Provable Advantage in Quantum PAC Learning
Wilfred Salmon, Sergii Strelchuk, Tom Gur
We revisit the problem of characterising the complexity of Quantum PAC learning, as introduced by Bshouty and Jackson [SIAM J. Comput. 1998, 28, 1136-1153]. Several quantum advanta…
Compression of metrological quantum information in the presence of noise
Flavio Salvati, Wilfred Salmon, Crispin H. W. Barnes +1
In quantum metrology, information about unknown parameters is accessed by measuring probe states . In experimental settings where co…
Only Classical Parameterised States have Optimal Measurements under Least Squares Loss
Wilfred Salmon, Sergii Strelchuk, David Arvidsson-Shukur
Measurements of quantum states form a key component in quantum-information processing. It is therefore an important task to compare measurements and furthermore decide if a measure…
