Universal cooling of quantum systems via randomized measurements
Josias Langbehn, George Mouloudakis, Emma King +5
Designing cooling protocols is believed to require knowledge of the system spectrum. In contrast, cooling in nature occurs whenever the system is coupled to a cold bath. How does n…
Shortcuts to adiabaticity with a quantum control field
Emma C. King, Giovanna Morigi, Raphaël Menu
Quantum adiabatic dynamics is the crucial element of adiabatic quantum computing and quantum annealing. Shortcuts to adiabaticity enable acceleration of the computational time by s…
Efficiency of classical simulations of a noisy Grover algorithm
Raphaël Menu, Johannes Schachenmayer
We analyze the modification of entanglement dynamics in the Grover algorithm when the qubits are subjected to single-qubit amplitude-damping or phase-flip noise. We compare quantum…
Speeding up Quantum Annealing with Engineered Dephasing
Mykolas Sveistrys, Josias Langbehn, Raphaël Menu +3
Building on the insight that engineered noise, specifically, engineered dephasing can enhance the adiabaticity of controlled quantum dynamics, we investigate how a dephasing-genera…
