Quantum field heat engine powered by phonon-photon interactions
Alessandro Ferreri, Vincenzo Macrì, Frank K. Wilhelm +2
We present a quantum heat engine based on a cavity with two oscillating mirrors that confine a quantum field as the working substance. The engine performs an Otto cycle during whic…
Post-processing noisy quantum computations utilizing N-representability constraints
Tomislav Piskor, Florian G. Eich, Michael Marthaler +2
We propose and analyze a method for improving quantum chemical energy calculations on a quantum computer impaired by decoherence and shot noise. The error mitigation approach relie…
Mean-Field Approximate Optimization Algorithm
Aditi Misra-Spieldenner, Tim Bode, Peter K. Schuhmacher +3
The Quantum Approximate Optimization Algorithm (QAOA) is suggested as a promising application on early quantum computers. Here, a quantum-inspired classical algorithm, the mean-fie…
Two qubits in one transmon -- QEC without ancilla hardware
Alexander Simm, Shai Machnes, Frank K. Wilhelm
We show that it is theoretically possible to use higher energy levels for storing and controlling two qubits within a superconducting transmon. This is done by identifying energy l…
