Quantum Computation
Harnessing quantum mechanics for exponential computational speedup
Digital Computing Works with Bits
-
N bits can represent 2N states 'one at a time.'
-
Parallel digital computing can speed up linearly at best.
Quantum Computing Works with Qubits
-
N qubits can represent a linear superposition of all 2N states 'at the same time.' → Exponentially large Hilbert space for computation.
-
Quantum computing can be exponentially larger and faster than digital computing.

Classical vs Quantum Computing
💻
Classical Bits
- State: 0 OR 1
- N bits = 2N states (one at a time)
- Linear parallelization
⚛️
Quantum Qubits
- State: Superposition of 0 AND 1
- N qubits = 2N states (simultaneously)
- Exponential parallelization
