## Quantum computing hardwares

- Maintaining coherence in quantum computers by W. G. Unruch (1995)
- M. Suchara et. al. arXiv:1312.2316 (2013)
- T2 times: coherence times of superconducting qubits
- Near-Term: Noisy Intermediate Scale Quantum Computing (NISQ), maybe ~100 qubits available, Preskil
- Noisy devices without full error correction, ~100qubits, decoherence, gate errors, measurement errors…
- algorithms need to be designed with noisy hardware in mind
- possible approach: short-depth circuits
- how could we deal with decoherence? PRL 119, 180509 (2017)
- quality is not abruptly degraded. It’s smooth. can be make the forgetting curve better like 1-exp(-x) ?
- probabilistic error cancellation, zero noise extrapolation
