The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor ...
A joint research team that included members from Tohoku University has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors.
One of the most counter-intuitive aspects of quantum physics is the idea that a quantum system, unlike a physical system governed by the everyday physics of the macroscopic universe, can exist in two states at once even if ...
Deep under the ground at Fermi National Accelerator Laboratory is a brand-new quantum sensor and computing research center called QUIET, and at the surface—100 meters above—sits its twin called LOUD.
They say that one can miss the forest for the trees. But it's often worth taking a closer look at the trees to make sense of the dense, brambly whole. That's what a Stanford University group did to tackle a thorny quantum-information ...
In support of the development of large-scale superconducting quantum computers, researchers with the National Institute of Advanced Industrial Science and Technology (AIST), one of the largest public research organizations ...
Quantum computers hold the promise of being able to quickly solve extremely complex problems that might take the world's most powerful supercomputer decades to crack.
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the "0" and the "1." However, spins in real devices also interact with light and vibrations ...
Quantum computers, computing devices that leverage the principles of quantum mechanics, could outperform classical computing on some complex optimization and processing tasks. In quantum computers, classical units of information ...
It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible.
