This is the first in a series of explainers on quantum technology. How it works, why it’s so powerful, and where it’s likely to be most useful first. By Martin Giles.
A quantum computer harnesses some of the almost-mystical phenomena of quantum mechanics to deliver huge leaps forward in processing power. Quantum machines promise to outstrip even the most capable of today’s – and tomorrow’s – supercomputers.
The secret to a quantum computer’s power lies in its ability to generate and manipulate quantum bits, or qubits. The article explains:
- What is a qubit?
- What is superposition?
- What is entanglement?
- What is decoherence?
- What is quantum supremacy?
- Where is a quantum computer likely to be most useful first?
The machines are also great for optimization problems because they can crunch through vast numbers of potential solutions extremely fast. Great read!
