Quantum computing: where the frontier stands
In short: A quantum computer represents and processes information using quantum states, potentially performing physical simulations or breaking encryption schemes.
Evidence class: Emerging research.
The basic unit of information, the qubit, serves a similar function as the bit in classical computing, but uses quantum states to process information.
What would need to be true? • Programming must compose operations so that the resulting program computes a useful result in theory and is implementable in practice. • Hardware must utilise coherent quantum states such that superposition, relative phase, and interference are part of the computation.
What could prevent it? • Current hardware implementations remain largely experimental and suitable for only certain specialised tasks.
