The working mechanism of quantum computers

You learned about qubits in the previous section. Now, to build quantum computers, physical qubits are built in a lab, and the quantum computer has an area that houses the qubits.

The unit that houses the qubits is kept at a temperature just above absolute zero to maximize the qubits' coherence and reduce interference. The low temperature helps to stabilize and control the qubits. A vacuum chamber can also be used to help minimize vibrations and stabilize the qubits. Signals can be sent to the qubits by using various methods, including microwaves, lasers, and voltage.

You must be wondering how quantum computers run so fast. A quantum computer runs so fast because it tries all answers to a problem in parallel. Is that true? Well, not really, not in the sense that multiple calculations are all happening in parallel universes. That said, qubits can hold 0 and 1 values at the same time using superposition, and let them influence...
