Practical Tomography of Multi-Time Processes
Abhinash Kumar Roy, Varun Srivastava, Christina Giarmatzi +1
Characterising multi-time quantum processes is essential for analysing temporally correlated noise and for designing effective control and mitigation strategies. A complete operati…

Multi-time quantum process tomography on a superconducting qubit
Christina Giarmatzi, Tyler Jones, Alexei Gilchrist +3
Current quantum technologies are at the cusp of becoming useful, but still face formidable obstacles such as noise. Noise severely limits the ability to scale quantum devices to th…

Hamiltonian characterisation of multi-time processes with classical memory
Kaumudibikash Goswami, Abhinash Kumar Roy, Varun Srivastava +4
A central problem in open quantum systems is the characterization of non-Markovian processes, where an environment retains the memory of its interaction with the system. A key dist…
