Quantum computing, a field that relies on the principles of quantum mechanics to calculate outcomes, has the potential to perform tasks too complex for traditional computers and to do so at high speeds, making it in some ways the new frontier for science and engineering. Precise control of qubits — or quantum bits, the basic ...
Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, optical quantum gates could be used for these purposes. But until now, it has not been possible to realize them with sufficient efficiency. By a sophisticated ...
Quantum computers harness some of the almost-mystical phenomena of quantum mechanics to deliver huge leaps forward in processing power. Quantum machines promise to outstrip even the most capable of today’s — and tomorrow’s — supercomputers. Quantum computers, as their name implies, operate on the bizarre principles of quantum mechanics to manipulate information and are poised ...
A new study indicates that qubits composed of holes may be the solution to the operational speed/coherence trade-off, potentially scaling up qubits to a mini-quantum computer. Quantum computers are predicted to be much more powerful and functional than today’s “classical” computers. One way to make a quantum bit is to use the “spin” of an ...
A study by NUST MISIS, the Russian Quantum Center, and the Karlsruhe Institute of Technology, published in npj Quantum Information, may pave the way for quantum computing. A Russian-German research team has created a quantum sensor that grants access to measurement and manipulation of individual two-level defects in qubits. In quantum computing, the information is encoded in qubits. Qubits (or quantum bits), the quantum mechanical analog of a classical ...
