Use of Faulty States in Cat-Code Error Correction
Michael Hanks, Soovin Lee, Nicolo Lo Piparo +4
Bosonic codes have seen a resurgence in interest for applications as varied as fault tolerant quantum architectures, quantum enhanced sensing, and entanglement distribution. Cat co…
High-precision and low-depth quantum algorithm design for eigenstate problems
Jinzhao Sun, Pei Zeng, Tom Gur +1
Estimating the eigenstate properties of quantum systems is a long-standing, challenging problem for both classical and quantum computing. Existing universal quantum algorithms typi…
Purification and correction of quantum channels by commutation-derived quantum filters
Sowmitra Das, Jinzhao Sun, Michael Hanks +2
Reducing errors is essential for reliable quantum computation. Quantum error mitigation (QEM) and quantum error correction (QEC) are two leading approaches for this task, each with…
Reshaping quantum device noise via repetition code circuits
Yue Ma, Michael Hanks, Evdokia Gneusheva +1
Noise of a quantum processor can be an important resource for simulating open quantum dynamics. However, this requires characterizing the device noise and then transforming it into…
