Quantum interference device for controlled two-qubit operations

Niels Jakob Søe Loft, Morten Kjaergaard, Lasse Bjørn Kristensen +5

Universal quantum computing relies on high-fidelity entangling operations. Here we demonstrate that four coupled qubits can operate as a quantum gate, where two qubits control the…

Coherent microwave photon mediated coupling between a semiconductor and a superconductor qubit

P. Scarlino, D. J. van Woerkom, U. C. Mendes +10

Semiconductor qubits rely on the control of charge and spin degrees of freedom of electrons or holes confined in quantum dots (QDs). They constitute a promising approach to quantum…

Challenging local realism with human choices

The BIG Bell Test Collaboration, C. Abellán, A. Acín +105

A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism. A Bell test requires spatially distributed entanglem…

Realization of efficient quantum gates with a superconducting qubit-qutrit circuit

T. Bækkegaard, L. B. Kristensen, N. J. S. Loft +3

Building a quantum computer is a daunting challenge since it requires good control but also good isolation from the environment to minimize decoherence. It is therefore important t…

Quantum spin transistors in superconducting circuits

N. J. S. Loft, L. B. Kristensen, C. K. Andersen +1

Transistors play a vital role in classical computers, and their quantum mechanical counterparts could potentially be as important in quantum computers. Where a classical transistor…
