QUANTUM COMPUTER Definition & Meaning

quantum computer

noun

a computer that makes use of the quantum states of electrons or other particles to store and process information as quantum bits.

quantum computer

noun

a type of computer which uses the ability of quantum systems to be in many different states at once, thus allowing it to perform many different computations simultaneously

quantum computer

A computer that exploits the quantum mechanical properties of superposition in order to allow a single operation to act on a large number of pieces of data. In a quantum computer, the data to be manipulated, represented in quantum bits, exists in all possible states simultaneously, in superposition. This allows a single operation to operate over all of these states at once, in contrast with a classical computer, which must carry out an operation for each state separately. Because of the difficulty of creating environments small enough for quantum effects to emerge but sufficiently isolated to prevent interaction with outside influences such as heat, only extremely rudimentary quantum computers currently exist, though algorithms for possible future devices are being developed.

Example Sentences

Although the paper describes the structure and architecture that could potentially be used to build a topological quantum computer, it’s not clear if all of these ingredients can be put together to actually construct the system, said Dr. Jelena Klinovaj, a theoretical physicist at the University of Basel who studies topology of quantum.

From

But it’s yet to be seen if all of the pieces necessary to make this form of quantum computer will come together into something with practical implications.

From

The idea is that the Majorana zero mode could be used to build a quantum computer, which could help scientists answer complex questions that standard computers are not capable of solving, with implications for medicine, cybersecurity and artificial intelligence.

From

Companies like Google, IBM and Amazon have invested in designing another form of quantum computer that uses chips built with “qubits,” or quantum bits.

From

In December, Google said its quantum computer could perform a calculation that a standard computer could complete in 10 septillion years — a period far longer than the age of the universe — in just under five minutes.
