Opportunities and challenges in scaling quantum error detection on hardware
Yanis Le Fur, Ethan Egger, Hong-Ye Hu +3
Quantum error detection can produce unbiased expectation values that exponentially converge to noiseless results as the code distance is increased. Despite this, its performance as…
Compressed Sensing for Efficient Fidelity Estimation of GHZ States
Farrokh Labib, David Nicholaeff, Vincent Russo +1
Accurately characterizing multipartite entangled states is a critical challenge in quantum information processing. In this work, we focus on applying compressed sensing techniques…
Towards violations of Local Friendliness with quantum computers
William J. Zeng, Farrokh Labib, Vincent Russo
Local Friendliness (LF) inequalities follow from seemingly reasonable assumptions about reality: (i) ``absoluteness of observed events'' (e.g., every observed event happens for all…
Quantum amplitude estimation from classical signal processing
Farrokh Labib, B. David Clader, Nikitas Stamatopoulos +1
We demonstrate that the problem of amplitude estimation, a core subroutine used in many quantum algorithms, can be mapped directly to a problem in signal processing called directio…
Quantum Risk Analysis of Financial Derivatives
Nikitas Stamatopoulos, B. David Clader, Stefan Woerner +1
We introduce two quantum algorithms to compute the Value at Risk (VaR) and Conditional Value at Risk (CVaR) of financial derivatives using quantum computers: the first by applying…
