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…
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…
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…
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…
Adiabatic quantum trajectories in engineered reservoirs
Emma C. King, Luigi Giannelli, Raphaël Menu +2
We analyze the efficiency of protocols for adiabatic quantum state transfer assisted by an engineered reservoir. The target dynamics is a quantum trajectory in the Hilbert space an…
Rise and fall of entanglement between two qubits in a non-Markovian bath
Sayan Roy, Christian Otto, Raphaël Menu +1
We analyse the dynamics of quantum correlations between two qubits coupled to a linear chain of oscillators. The chain mediates interactions between the qubits and acts as a non-Ma…
Reservoir-engineering shortcuts to adiabaticity
Raphaël Menu, Josias Langbehn, Christiane P. Koch +1
We propose a protocol that achieves fast adiabatic transfer between two orthogonal states of a qubit by coupling with an ancilla. The qubit undergoes Landau-Zener dynamics, whereas…
