Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics—or ...

Qubits -- the fundamental units of quantum information -- drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they ...

Tsvetan Ivanov, researcher at IMEC, says, "We have demonstrated in our lab superconducting qubits with coherence times exceeding 100 µs and an average single-qubit gate fidelity of 99.94%.

To demonstrate that quantum information is preserved as it propagates through a random walk, a group of researchers strung together a string of 12 superconducting qubits. The researchers set the ...

Physics Superconducting qubits have passed a key quantum test. A Bell test can confirm whether two systems are truly entangled – it has now been used to confirm entanglement between qubits in a ...

Superconducting qubits coupled to ferromagnetic materials via microwave cavities enable precise characterization of magnon number and lifetimes, even with thousands of excitations.

In one of two papers published in Science, Robert McDermott of University of Wisconsin-Madison and colleagues in Wisconsin and New York describe a new detector for reading-out superconducting qubits.

Current approaches to create superconducting qubits for quantum computers yield chips that are substantially larger than those found in classical computers. To shrink things down, researchers have ...

The superconducting qubits are numbered 1–10 and the central bus resonator is labelled "B". The red and blue structures are control lines for the individual qubits. (Courtesy: Chao Song et ...
