April 29, 2015 /PRNewswire/ -- IBM (NYSE: IBM) scientists today unveiled two critical advances towards the realization of a practical quantum computer
practical quantum computer
, which would need to be in the dozens-of-qubits
In addition to a practical quantum computer
, Lukin envisions the system being used in applications that include "quantum cash" (a payment system for bank transactions and credit cards that relies on the coding of quantum bits to thwart counterfeiters) and quantum networks (a highly secure communications method that uses quantum bits to transmit data).
ISLAMABAD, August 10, 2009 (Balochistan Times): Physicists at the National Institute of Standards and Technology (NIST), US, have demonstrated sustained, reliable information processing operations on electrically charged atoms (ions), thus raising prospects for building a practical quantum computer
REMOTE ENTANGLEMENT Entangling a few qubits is a good step, but a practical quantum computer
will need to have dozens or even hundreds of them.
Technology achieving control of the coupling strength between qubits is vital to the realization of a practical quantum computer
, and has been long awaited in the scientific field.
Since a practical quantum computer
will require extended coherent times, a detailed investigation and understanding of all possible decoherence modes is important.
NEC and JST researchers expect that a practical quantum computer
is now a significant step closer with the development of coherent control of quantum states in a solid-state electron device.
