Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Benchmarking Optimization Algorithms for Automated Calibration of Quantum Devices
Kevin Pack, Shai Machnes, Frank K. Wilhelm
We present the results of a comprehensive study of optimization algorithms for the calibration of quantum devices. As part of our ongoing efforts to automate bring-up, tune-up, and…
Demolition measurement protocol for transmon qubits
Ashutosh Mishra, Frank K. Wilhelm, Shai Machnes
The process of measuring a qubit and re-initializing it to the ground state practically lead to long qubit idle times between re-runs of experiments on a superconducting quantum co…
Co-designing Transmon devices for control with simple pulses
Nicolas Wittler, Shai Machnes, Frank K. Wilhelm
In the current NISQ era, there is demand for functional quantum devices to solve relevant computational problems, which motivates a utilitarian perspective on device design: The go…
Non-Markovian Ensemble Propagation
Miralem Sinanović, Alessandro Ciani, Shai Machnes +1
Open quantum systems are ubiquitous in nature and central to quantum technologies. A common description of their dynamics is given by the celebrated Lindblad master equation, which…
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…
