Quantum computer hardware
Quantum computer hardware includes qubits, quantum gates, and physical qubit hardware. Qubits are the basic units of quantum computing.
Qubits
- The basic units of quantum computing
- Fragile and susceptible to environmental interference
- Superconducting qubits are made of tiny loops of superconducting material called Josephson junctions
- Topological qubits are theorized to be more stable than other qubits
Quantum gates
- Quantum gates must be reversible because quantum mechanics is reversible
Physical qubit hardware
- Surface code error correction uses many physical qubits to represent a single logical qubit
- Trapped ions provide longer coherence durations
Companies involved in quantum computing
Intel
Has released a 12-qubit silicon chip called Tunnel Falls. Intel also released a quantum software development kit (SDK).
PsiQuantum
A quantum computing company that aims to build the world's first useful quantum computer
