Quantum Enhanced Dark-Matter Search with Entangled Fock States in High-Quality Cavities
Benjamin Freiman, Xinyuan You, Andy C. Y. Li +5
We present a quantum-enhanced protocol for detecting wave-like dark matter using an array of entangled superconducting cavities initialized in an -photon Fock state. By dist…

Floquet-engineered fast SNAP gates in weakly coupled circuit-QED systems
Xinyuan You, Andy C. Y. Li, Tanay Roy +5
Superconducting cavities with high quality factors, coupled to a fixed-frequency transmon, provide a state-of-the-art platform for quantum information storage and manipulation. The…

Practical limitations of the switching theorem for adiabatic state preparation
Thomas D. Cohen, Andrew Li, Hyunwoo Oh +1
The viability of adiabatic quantum computation depends on the slow evolution of the Hamiltonian. The adiabatic switching theorem provides an asymptotic series for error estimates i…
