Experimental measurement and a physical interpretation of quantum shadow enumerators
Daniel Miller, Kyano Levi, Lukas Postler +18
Throughout its history, the theory of quantum error correction has heavily benefited from translating classical concepts into the quantum setting. In particular, classical notions…
The abelian state hidden subgroup problem: Learning stabilizer groups and beyond
Marcel Hinsche, Jens Eisert, Jose Carrasco
Identifying the symmetry properties of quantum states is a central theme in quantum information theory and quantum many-body physics. In this work, we investigate quantum learning…
Mind the gaps: The fraught road to quantum advantage
Jens Eisert, John Preskill
Quantum computing is advancing rapidly, yet substantial gaps separate today's noisy intermediate-scale quantum (NISQ) devices from tomorrow's fault-tolerant application-scale quant…
Holonomic quantum computation: a scalable adiabatic architecture
Clara Wassner, Tommaso Guaita, Jens Eisert +1
Holonomic quantum computation exploits the geometric evolution of eigenspaces of a degenerate Hamiltonian to implement unitary evolution of computational states. In this work we in…
Measurement-driven quantum advantages in shallow circuits
Chenfeng Cao, Jens Eisert
Quantum advantage schemes probe the boundary between classically simulatable and classically intractable quantum dynamics. We explore the impact of mid-circuit measurements on the…
Phase shadow: A noise-tolerant path to global quantum property estimation
Qingyue Zhang, Dayue Qin, Zhou You +3
Measuring global quantum properties-such as the fidelity to complex multipartite states-is both an essential and experimentally challenging task. Classical shadow estimation offers…
