D-Wave is the only company selling a quantum computer. It sold its first system in 2011 and is now pushing the speed limits with a new quantum computer called the D-Wave 2000Q, which has 2,000 qubits.
The 2000Q is twice the size of its current 1,000-qubit D-Wave 2X, which is considered one of the most advanced computers in the world today. A price tag for the 2000Q wasn’t available.
The 2000Q is thousands of times faster than its predecessor and is leagues ahead in performance compared to today’s PCs. The specialized computer, valued at roughly $15 million, will first ship out to Temporal Defense Systems, which will use the system to tackle cybersecurity threats.
D-Wave’s quantum computers are being already used by the Los Alamos National Laboratory, Google, NASA, and Lockheed Martin. D-Wave’s goal is to upgrade all those systems.
