Quantum quench dynamics as a shortcut to adiabaticity
Alexander Lukin, Benjamin F. Schiffer, Boris Braverman +9
The ability to efficiently prepare ground states of quantum Hamiltonians via adiabatic protocols is typically limited by the smallest energy gap encountered during the quantum evol…

Phase-Sensitive Quantum Measurement without Controlled Operations
Yilun Yang, Arthur Christianen, Mari Carmen Bañuls +2
Many quantum algorithms rely on the measurement of complex quantum amplitudes. Standard approaches to obtain the phase information, such as the Hadamard test, give rise to large ov…
