Realization of a quantum neural network using repeat-until-success circuits in a superconducting quantum processor
M. S. Moreira, G. G. Guerreschi, W. Vlothuizen +14
Artificial neural networks are becoming an integral part of digital solutions to complex problems. However, employing neural networks on quantum processors faces challenges related…
Schrödinger cat states of a 16-microgram mechanical oscillator
Marius Bild, Matteo Fadel, Yu Yang +4
The superposition principle is one of the most fundamental principles of quantum mechanics. According to the Schrödinger equation, a physical system can be in any linear combinatio…
Logical-qubit operations in an error-detecting surface code
J. F. Marques, B. M. Varbanov, M. S. Moreira +10
We realize a suite of logical operations on a distance-two logical qubit stabilized using repeated error detection cycles. Logical operations include initialization into arbitrary…
Variational preparation of finite-temperature states on a quantum computer
R. Sagastizabal, S. P. Premaratne, B. A. Klaver +13
The preparation of thermal equilibrium states is important for the simulation of condensed-matter and cosmology systems using a quantum computer. We present a method to prepare suc…
High-fidelity controlled-Z gate with maximal intermediate leakage operating at the speed limit in a superconducting quantum processor
V. Negîrneac, H. Ali, N. Muthusubramanian +9
We introduce the sudden variant (SNZ) of the Net Zero scheme realizing controlled- (CZ) gates by baseband flux control of transmon frequency. SNZ CZ gates operate at the speed l…
Protecting quantum entanglement from leakage and qubit errors via repetitive parity measurements
C. C. Bultink, T. E. O'Brien, R. Vollmer +9
Protecting quantum information from errors is essential for large-scale quantum computation. Quantum error correction (QEC) encodes information in entangled states of many qubits,…
