Quantum Computer


Quantum computer, the next generation computer

A quantum computer is any device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data.

What is a qubit?

Today’s computers use bits—a stream of electrical or optical pulses representing 1s or 0s. Quantum computers, on the other hand, use qubits, which are typically subatomic particles such as electrons or photons.

What is superposition?

Qubits can represent numerous possible combinations of and at the same time. This ability to simultaneously be in multiple states is called superposition. To put qubits into superposition, researchers manipulate them using precision lasers or microwave beams.

What is entanglement?

Researchers can generate pairs of qubits that are “entangled,” which means the two members of a pair exist in a single quantum state. Changing the state of one of the qubits will instantaneously change the state of the other one in a predictable way. This happens even if they are separated by very long distances.

How will a quantum computer be used?

One of the most promising applications of quantum computers is for simulating the behavior of matter down to the molecular level. Auto manufacturers like Volkswagen and Daimler are using quantum computers to simulate the chemical composition of electrical-vehicle batteries to help find new ways to improve their performance.

We are still in process of developing

considerable work still needs to be done before quantum computers can become an important part of our everyday lives. For example, he wrote, researchers will have to develop new algorithms that can work with the error-prone quantum processors that will be available in the near future.
