Quantum computers

**Quantum computers are machines that use the properties of quantum physics to store data and perform computations.**- Classical computers, which include smartphones and laptops, encode information in binary
**“bits”**that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a**quantum bit or qubit.**Qubits are made using physical systems, such as the spin of an electron or the orientation of a photon. - These systems can be in many different arrangements all at once,
**a property known as quantum superposition.**Qubits can also be inextricably linked together using a phenomenon called**quantum entanglement**. The result is that a series of qubits can represent different things simultaneously.
