Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.
Physicists from MIPT and the Russian Quantum Center have developed an easier method to create a universal quantum computer using multilevel quantum systems (qudits), each one of which is able to work with multiple "conventional" ...
A breakthrough into the full characterisation of quantum states has been published today as a prestigious Editors' Suggestion in the journal Physical Review Letters.
Much of the current research on the development of a quantum computer involves work at very low temperatures. The challenge to make them more practical for everyday use is to make them work at room temperature.
What happens when you combine the pure tones of an internationally renowned mezzo soprano and the complex technology of a $15million quantum supercomputer?
Jarrod McClean and his Lawrence Berkeley National Laboratory colleagues want to simulate and predict the chemistry and properties of advanced compounds before scientists go into the lab to make them.
The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing ...
