Thermodynamic limitations on fault-tolerant quantum computing
Mykhailo Bilokur, Sarang Gopalakrishnan, Shayan Majidy
We investigate the thermodynamic limits on scaling fault-tolerant quantum computers due to heating from quantum error correction (QEC). Quantum computers require error correction,…
Stabilizing Non-Abelian Topological Order against Heralded Noise via Local Lindbladian Dynamics
Sanket Chirame, Abhinav Prem, Sarang Gopalakrishnan +1
An important open question for the current generation of highly controllable quantum devices is understanding which phases can be realized as stable steady-states under local quant…
Spontaneous Strong Symmetry Breaking in Open Systems: Purification Perspective
Pablo Sala, Sarang Gopalakrishnan, Masaki Oshikawa +1
We explore the landscape of the decoherence effect in mixed-state ensembles from a purification perspective. We analyze the spontaneous strong-to-weak symmetry breaking (SSSB) in m…
Characterizing MPS and PEPS Preparable via Measurement and Feedback
Yifan Zhang, Sarang Gopalakrishnan, Georgios Styliaris
Preparing long-range entangled states poses significant challenges for near-term quantum devices. It is known that measurement and feedback (MF) can aid this task by allowing the p…
Stable Symmetry-Protected Topological Phases in Systems with Heralded Noise
Sanket Chirame, Fiona J. Burnell, Sarang Gopalakrishnan +1
We present a family of local quantum channels whose steady-states exhibit stable mixed-state symmetry-protected topological (SPT) order. Motivated by recent experimental progress o…
