Heisenberg-limited metrology in the presence of non-Markovian noise with finite control rates
Shravan Shravan, Tyler G. Thurtell
Recently, it has been shown that protocols utilizing infinitely fast controls, such as quantum error correction, can in principle restore Heisenberg-limited frequency estimation in…

Adaptive quantum metrology with large dynamic range using short one-axis twists
Tyler G. Thurtell, Akimasa Miyake
Phase estimation with potentially large phase values, i.e., with large dynamic range, has many applications in quantum metrology, for example to atomic clocks. A recently proposed…

Holstein Primakoff spin codes for local and collective noise
Sivaprasad Omanakuttan, Tyler Thurtell, Andrew K. Forbes +2
Quantum error correction is essential for fault-tolerant quantum computation, yet most existing codes rely on local control and stabilizer measurements that are difficult to implem…
