Multi-Layer Cycle Benchmarking for high-accuracy error characterization
Alessio Calzona, Miha Papič, Pedro Figueroa-Romero +1
Accurate noise characterization is essential for reliable quantum computation. Effective Pauli noise models have emerged as powerful tools, offering detailed description of the err…
Estimating the coherence of noise in mid-scale quantum systems
Pedro Figueroa-Romero, Miha Papič, Adrian Auer +1
While the power of quantum computers is commonly acknowledged to rise exponentially, it is often overlooked that the complexity of quantum noise mechanisms generally grows much fas…
Machine Learning of Average Non-Markovianity from Randomized Benchmarking
Shih-Xian Yang, Pedro Figueroa-Romero, Min-Hsiu Hsieh
The presence of correlations in noisy quantum circuits will be an inevitable side effect as quantum devices continue to grow in size and depth. Randomized Benchmarking (RB) is argu…
Towards a general framework of Randomized Benchmarking incorporating non-Markovian Noise
Pedro Figueroa-Romero, Kavan Modi, Min-Hsiu Hsieh
The rapid progress in the development of quantum devices is in large part due to the availability of a wide range of characterization techniques allowing to probe, test and adjust…
Equilibration of Multitime Quantum Processes in Finite Time Intervals
Neil Dowling, Pedro Figueroa-Romero, Felix A. Pollock +2
A generic non-integrable (unitary) out-of-equilibrium quantum process, when interrogated across many times, is shown to yield the same statistics as an (non-unitary) equilibrated p…
Relaxation of Multitime Statistics in Quantum Systems
Neil Dowling, Pedro Figueroa-Romero, Felix A. Pollock +2
Equilibrium statistical mechanics provides powerful tools to understand physics at the macroscale. Yet, the question remains how this can be justified based on a microscopic quantu…
Equilibration and Typicality in Quantum Processes
Pedro Figueroa-Romero
Forgetfulness is a common feature of nature. Moreover, without forgetfulness, repeatability would be impossible. Despite this, small systems constantly leak information about their…
Markovianization with approximate unitary designs
Pedro Figueroa-Romero, Felix A. Pollock, Kavan Modi
Memoryless processes are ubiquitous in nature, in contrast with the mathematics of open systems theory, which states that non-Markovian processes should be the norm. This discrepan…
Equilibration on average in quantum processes with finite temporal resolution
Pedro Figueroa-Romero, Kavan Modi, Felix A. Pollock
We characterize the conditions under which a multi-time quantum process with a finite temporal resolution can be approximately described by an equilibrium one. By providing a gener…
Almost Markovian processes from closed dynamics
Pedro Figueroa-Romero, Kavan Modi, Felix A. Pollock
It is common, when dealing with quantum processes involving a subsystem of a much larger composite closed system, to treat them as effectively memory-less (Markovian). While open s…
