Pseudomagic Quantum States
Andi Gu, Lorenzo Leone, Soumik Ghosh +3
Notions of nonstabilizerness, or "magic", quantify how non-classical quantum states are in a precise sense: states exhibiting low nonstabilizerness preclude quantum advantage. We i…
Effect of non-unital noise on random circuit sampling
Bill Fefferman, Soumik Ghosh, Michael Gullans +2
In this work, drawing inspiration from the type of noise present in real hardware, we study the output distribution of random quantum circuits under practical non-unital noise sour…
Aging during Phase Separation in Long-Range Ising Model
Soumik Ghosh, Subir K. Das
The kinetics of domain growth and aging in conserved order parameter systems, in the presence of short-range interaction, is widely studied. Due to technical difficulties and lack…
Sharp complexity phase transitions generated by entanglement
Soumik Ghosh, Abhinav Deshpande, Dominik Hangleiter +2
Entanglement is one of the physical properties of quantum systems responsible for the computational hardness of simulating quantum systems. But while the runtime of specific algori…
Quantum Pseudoentanglement
Scott Aaronson, Adam Bouland, Bill Fefferman +4
Entanglement is a quantum resource, in some ways analogous to randomness in classical computation. Inspired by recent work of Gheorghiu and Hoban, we define the notion of "pseudoen…
