Precision Bounds on Continuous-Variable State Tomography using Classical Shadows
Srilekha Gandhari, Victor V. Albert, Thomas Gerrits +2
Shadow tomography is a framework for constructing succinct descriptions of quantum states using randomized measurement bases, called classical shadows, with powerful methods to bou…
Continuous-variable quantum state designs: theory and applications
Joseph T. Iosue, Kunal Sharma, Michael J. Gullans +1
We generalize the notion of quantum state designs to infinite-dimensional spaces. We first prove that, under the definition of continuous-variable (CV) state -designs from Comm.…
Quantum Non-Demolition Photon Counting in a 2d Rydberg Atom Array
Christopher Fechisin, Kunal Sharma, Przemyslaw Bienias +4
Rydberg arrays merge the collective behavior of ordered atomic arrays with the controllability and optical nonlinearities of Rydberg systems, resulting in a powerful platform for r…
Crystalline Quantum Circuits
Grace M. Sommers, David A. Huse, Michael J. Gullans
Random quantum circuits continue to inspire a wide range of applications in quantum information science and many-body quantum physics, while remaining analytically tractable throug…
Neural-Network Decoders for Measurement Induced Phase Transitions
Hossein Dehghani, Ali Lavasani, Mohammad Hafezi +1
Open quantum systems have been shown to host a plethora of exotic dynamical phases. Measurement-induced entanglement phase transitions in monitored quantum systems are a striking e…
Clifford-deformed Surface Codes
Arpit Dua, Aleksander Kubica, Liang Jiang +2
Various realizations of Kitaev's surface code perform surprisingly well for biased Pauli noise. Attracted by these potential gains, we study the performance of Clifford-deformed su…
