Efficient certification of time-reversal symmetry requires entanglement
Zhenhuan Liu, Zhenyu Du, Yifan Tang +3
Time-reversal symmetry is a fundamental principle of physics describing the invariance of physical laws under reversal of the direction of time. We formulate a Bell-inequality-like…
Fermionic quantum error correction is never free
Yifan Tang, Ingo Roth, Philippe Faist +3
Fermionic platforms offer compelling architectures for quantum computing, ranging from topologically protected Majorana-based qubits to fermionic cold atoms. To achieve scalability…
Witness expansion: A unified framework for analytical and measurable mixed-state resource detection
Yifan Tang, Chengkai Zhu, Yuzhen Zhang +6
Quantum information science aims to harness different kinds of quantum resources to accomplish specific information-processing tasks. These resources also play an increasingly impo…
Local robust shadows on a trapped ion computer -- a case study
Jadwiga Wilkens, Milena Guevara-Bertsch, Marwa Marso +6
We experimentally demonstrate local robust shadows on a trapped-ion quantum computing system, a protocol developed to counteract measurement errors. We alternate between a calibrat…
Scalable Determination of Penalization Weights for Constrained Optimizations on Approximate Solvers
Edoardo Alessandroni, Sergi Ramos-Calderer, Michel Krispin +7
Quadratic unconstrained binary optimization (QUBO) provides problem formulations for various computational problems that can be solved with dedicated QUBO solvers, based on classic…
Triangle Criterion: a mixed-state magic criterion with applications in distillation and detection
Zhenhuan Liu, Tobias Haug, Qi Ye +2
We introduce a mixed-state magic criterion, the Triangle Criterion, which plays a role for magic analogous to the Positive Partial Transposition (PPT) Criterion for entanglement: i…
Robust ultra-shallow shadows
Renato M. S. Farias, Raghavendra D. Peddinti, Ingo Roth +1
We present a robust shadow estimation protocol for wide classes of low-depth measurement circuits that mitigates noise as long as the effective measurement map including noise is l…
Noise-mitigated randomized measurements and self-calibrating shadow estimation
E. Onorati, J. Kitzinger, J. Helsen +4
Randomized measurements are increasingly appreciated as powerful tools to estimate properties of quantum systems, e.g., in the characterization of hybrid classical-quantum computat…
Stability of classical shadows under gate-dependent noise
Raphael Brieger, Markus Heinrich, Ingo Roth +1
Expectation values of observables are routinely estimated using so-called classical shadows$\unicode{x2014}$the outcomes of randomized bases measurements on a repeatedly prepared q…
