The fragile qubits that make up quantum computers offer a powerful computational tool, yet also present a conundrum: How can engineers create practical, workable quantum systems out of bits that are so easily disturbed—and ...
Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now ...
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. ...
Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional ...
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain ...
By modifying a refrigerator commonly used in both research and industry, researchers at the National Institute of Standards and Technology (NIST) have drastically reduced the time and energy required to cool materials to ...
Researchers simulated a key quantum state at one of the largest scales reported, with support from the Quantum Computing User Program, or QCUP, at the Department of Energy's Oak Ridge National Laboratory.
Quantum computers, systems that process and store information leveraging quantum mechanical phenomena, could eventually outperform classical computers on numerous tasks. Among other things, these computers could allow researchers ...
It's Saturday, which means that in a universe where the arrow of time moves backward, people have to go to work tomorrow. In such a hypothetical universe, Garfield hates Fridays—tough to imagine. This week, we looked at ...
Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering.
