Optimized Quantum States for Sensing in the Presence of Loss and Phase Noise
Shruti Maliakal, Zachary Mann, Christopher Wipf +3
Squeezed vacuum lets gravitational-wave detectors and other quantum sensors surpass the standard quantum limit, and is optimal in the loss-limited regime; phase noise breaks this o…
Chutes and Ladders: Dynamical Automorphisms via the ZX-Calculus
Alexander Frei, Sascha Zakaib-Bernier, Zachary Mann +2
The ZX-calculus is a powerful graphical language for manipulating quantum circuits, which has recently found many applications in quantum error correction. We extend this language…
Towards sample-optimal learning of bosonic Gaussian quantum states
Senrui Chen, Francesco Anna Mele, Marco Fanizza +5
Continuous-variable systems enable key quantum technologies in computation, communication, and sensing. Bosonic Gaussian states emerge naturally in various such applications, inclu…
Quantum Error Corrected Non-Markovian Metrology
Zachary Mann, Ningping Cao, Raymond Laflamme +1
Quantum metrology aims to maximize measurement precision on quantum systems, with a wide range of applications in quantum sensing. Achieving the Heisenberg limit (HL) - the fundame…
