Physical implementations of quantum computers today, such as those using semiconduction technology, must operate at close to absolute zero temperature in a highly isolated environment.
Physical implementations of quantum computers today, such as those using semiconduction technology, must operate at close to absolute zero temperature in a highly isolated environment. Related areas like quantum communication (notably quantum cryptography) and quantum sensing do not rely on a large number of qubits to operate. As an interesting twist, while quantum computing may potentially make current encryption schemes unsecure, quantum cryptography would be a way to provide fundamentally secure encryption schemes.12
