Universal Counterdiabatic Quantum Sensing
Stewart Morawetz, Anatoli Polkovnikov
One of the primary applications of quantum mechanics is leveraging coherence to make incredibly sensitive measurements. One way to push the boundary of this sensitivity even furthe…
Universal Counterdiabatic Driving
Stewart Morawetz, Anatoli Polkovnikov
Local counterdiabatic (CD) driving provides a systematic way of constructing a control protocol to approximately suppress the excitations resulting from changing some parameter(s)…
The Moving Born-Oppenheimer Approximation
Bernardo Barrera, Daniel P. Arovas, Anushya Chandran +1
We develop a mixed quantum-classical framework, dubbed the Moving Born-Oppenheimer Approximation (MBOA), to describe the dynamics of slow degrees of freedom (DOFs) coupled to fast…
Efficient Paths for Local Counterdiabatic Driving
Stewart Morawetz, Anatoli Polkovnikov
Local counterdiabatic driving (CD) provides a feasible approach for realizing approximate reversible/adiabatic processes like quantum state preparation using only local controls an…
Robust effective ground state in a nonintegrable Floquet quantum circuit
Tatsuhiko N. Ikeda, Sho Sugiura, Anatoli Polkovnikov
An external periodic (Floquet) drive is believed to bring any initial state to the featureless infinite temperature state in generic nonintegrable isolated quantum many-body system…
Counterdiabatic Optimised Local Driving
Ieva Čepaitė, Anatoli Polkovnikov, Andrew J. Daley +1
Adiabatic protocols are employed across a variety of quantum technologies, from implementing state preparation and individual operations that are building blocks of larger devices,…
