Optimal discrimination of quantum sequences

Tathagata Gupta, Shayeef Murshid, Vincent Russo +1

A key concept of quantum information theory is that accessing information encoded in a quantum system requires us to discriminate between several possible states the system could b…

Locally distinguishing a maximally entangled basis using shared entanglement

Somshubhro Bandyopadhyay, Vincent Russo

We consider the problem of distinguishing between the elements of a bipartite maximally entangled orthonormal basis using local operations and classical communication (LOCC) and a…

Quantum error mitigation by layerwise Richardson extrapolation

Vincent Russo, Andrea Mari

A widely used method for mitigating errors in noisy quantum computers is Richardson extrapolation, a technique in which the overall effect of noise on the estimation of quantum exp…

Counting collisions in random circuit sampling for benchmarking quantum computers

Andrea Mari

We show that counting the number of collisions (re-sampled bitstrings) when measuring a random quantum circuit provides a practical benchmark for the quality of a quantum computer…

Tight bounds for antidistinguishability and circulant sets of pure quantum states

Nathaniel Johnston, Vincent Russo, Jamie Sikora

A set of pure quantum states is said to be antidistinguishable if upon sampling one at random, there exists a measurement to perfectly determine some state that was not sampled. We…

Increasing the Measured Effective Quantum Volume with Zero Noise Extrapolation

Elijah Pelofske, Vincent Russo, Ryan LaRose +5

Quantum Volume is a full-stack benchmark for near-term quantum computers. It quantifies the largest size of a square circuit which can be executed on the target device with reasona…
