What is Quantum Computer?
Quantum computer is a Computer which makes use of the quantum states of subatomic particles to store information. Quantum computers are different from binary digital electronic computers based on transistors.
Quantum computers can theoretically be so much faster because they take advantage of quantum mechanics.
While traditional computers use the “bits” to represent information as a 0 or a 1, quantum computers use “qubits” to represent information as a 0, 1, or both at the same time. This allows Quantum computers to achieve a correct answer much faster and efficiently through parallel processing.
A quantum computer with just 50 qubits will be much more powerful than any supercomputer available today.
Quantum Computers – Soon A Reality!
Quantum computers are expected to take the computing technology to the highest level, but it is an experimental and enormously complex technology that Google and NASA are working on .
Google and NASA (National Aeronautics and Space Administration) bought a D-Wave 2X quantum computer.
Google Quantum Artificial Intelligence Lab has announced that its D-Wave machine is considerably much faster than simulated annealing – quantum computation simulation on a conventional computer with a single core processor.
The tests on D-Wave machines using Quantum Monte Carlo algorithm simulates running an optimization problem on ordinary silicon, and again the results were more than 100 times faster than a conventional computer.
IBM Scientists launches the world’s first cloud-based quantum computing technology, IBM Quantum Experience, for anyone to use. It is an online simulator that lets anyone run algorithms and experiments on the company’s five-qubit quantum computer.
Now any one can now access IBM’s five-qubit quantum computing processor, which is located at its a research center in Yorktown Heights, New York, through the cloud to run experiments and test applications. We need to request an invitation from IBM through a web form.
IBM’s qubit processor is the world’s first quantum processor accessible to the public, even if through the cloud.
Users who want to access the quantum processor can stay in the comfort of their homes or offices and work with qubits, study tutorials, and run simulations using the cloud and their computers or mobile devices.
