Non-Abelian topological order and anyons on a trapped-ion processor
Non-Abelian topological order is a coveted state of matter with remarkable properties,
including quasiparticles that can remember the sequence in which they are exchanged …

Probing postmeasurement entanglement without postselection
SJ Garratt, E Altman - PRX Quantum, 2024 - APS
We study the problem of observing quantum collective phenomena emerging from large
numbers of measurements. These phenomena are difficult to observe in conventional …

Symmetry-Enforced Entanglement in Maximally Mixed States
Entanglement in quantum many-body systems is typically fragile to interactions with the
environment. Generic unital quantum channels, for example, have the maximally mixed state …

Realizing the Nishimori transition across the error threshold for constant-depth quantum circuits
Preparing quantum states across many qubits is necessary to unlock the full potential of
quantum computers. However, a key challenge is to realize efficient preparation protocols …

Measurement-induced phase transitions in the toric code
We show how distinct phases of matter can be generated by performing random single-qubit
measurements on a subsystem of toric code. Using a parton construction, such …
