Symmetry as a route to generalized bosonic Kitaev chains
Gideon Lee, Tony Jin, Aashish A. Clerk
The bosonic Kitaev chain (BKC) model is a deceptively simple looking quadratic pairing Hamiltonian. Despite being purely Hermitian, it exhibits a number of striking non-Hermitian t…
Gauging the Spacetime Code
Gideon Lee
In recent years, the spacetime code has arisen as a candidate for a unifying view of fault tolerance in space and time. On the other hand, the recent study of dynamical phases has…
Quantum superresolution and noise spectroscopy with quantum computing
James W. Gardner, Federico Belliardo, Gideon Lee +2
Quantum metrology of an incoherent signal is a canonical sensing problem related to superresolution and noise spectroscopy. We show that quantum computing can accelerate searches f…
Timescales, Squeezing and Heisenberg Scalings in Many-Body Continuous Sensing
Gideon Lee, Ron Belyansky, Liang Jiang +1
The continuous monitoring of driven-dissipative systems offers new avenues for quantum advantage in metrology. This approach mixes temporal and spatial correlations in a manner dis…
Implementation of a quantum addressable router using superconducting qubits
Connie Miao, Sébastien Léger, Ziqian Li +3
The implementation of a quantum router capable of performing both quantum signal routing and quantum addressing (a Q2-router) represents a key step toward building quantum networks…
Analysis and Suppression of Errors in Quantum Random Access Memory under Extended Noise Models
Rohan Mehta, Gideon Lee, Liang Jiang
Quantum random access memory (QRAM) is required for numerous quantum algorithms and network architectures. Previous work has shown that the ubiquitous bucket-brigade QRAM is highly…
