Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high ...
A team of engineers and physicists at quantum computing company Quantinuum has conducted the first-ever teleportation of a logical qubit using fault-tolerant methods. In their paper published in the journal Science, the group ...
Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements ...
Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have shown that a type of qubit whose architecture is more amenable to mass production can perform comparably to qubits currently dominating ...
A team of computer scientists at Google Quantum AI has demonstrated a type of quantum memory for a quantum computer that produces far fewer errors than others. The group has published a paper on the arXiv preprint server ...
Researchers have demonstrated a new multi-functional device that could help advance the scalability of solid-state color centers, enabling them to be used in larger and more complex quantum computers and networks. As efficient ...
Solving the problem of error is essential for the practical application of quantum computing technologies that surpass the performance of digital computers. Information input into a qubit, the smallest unit of quantum computation, ...
In work published in Science Advances, Hayato Goto from the RIKEN Center for Quantum Computing in Japan has proposed a new quantum error correction approach using what he calls "many-hypercube codes."
Before quantum computers can solve complex problems, researchers must develop technologies that manage larger numbers of qubits (the building blocks of quantum computers) for extended periods. Neutral atoms play an important ...
Â鶹ÒùÔºicists from Aalto University in Finland, alongside an international team of collaborators, have theoretically and experimentally shown that superconducting qubit coherence loss can be directly measured as thermal dissipation ...
