A Qutrit Time Crystal Stabilized with Native Chiral Interactions
Noah Goss, Nishchay Suri, Brian Marinelli +11
Periodically driven quantum many-body systems can spontaneously break discrete time-translation symmetry, realizing discrete time crystals. To date, both experimental and theoretic…

Quantum Sensing using Geometrical Phase in Qubit-Oscillator Systems
Nishchay Suri, Zhihui Wang, Tanay Roy +2
We present a quantum sensing protocol for coupled qubit-oscillator systems that surpasses the standard quantum limit (SQL) by exploiting a geometrical phase. The signal is encoded…

Uniformly Decaying Subspaces for Error Mitigated Quantum Computation
Nishchay Suri, Jason Saied, Davide Venturelli
We present a general condition to obtain subspaces that decay uniformly in a system governed by the Lindblad master equation and use them to perform error mitigated quantum computa…
