Surviving readout errors and incomplete postselection in monitored quantum circuits
Murtaza Ali Mir, Teemu Ojanen, Ali G. Moghaddam
We study how readout errors affect dynamics in monitored quantum circuits. Such errors make postselection effectively incomplete, conditioning trajectories on imperfect rather than…
The ebbs and flows of quantum learning and sensing
Matias Karjula, Teemu Ojanen, Tapio Ala-Nissila +1
What is the relation between subsystem quantum complexity and the emergence of computationally useful structure? We address this by studying a family of minimally tunable postvaria…
Postselection-free ballistic-diffusive transition in monitored spin chains
K. G. S. H. Gunawardana, Ali G. Moghaddam, Teemu Ojanen
We study spin and entanglement dynamics in spin-1/2 XXZ chains under periodic monitoring and show that this system exhibits two measurement-induced phase transitions: a steady-stat…
Experimental high-dimensional multi-qubit Bell non-locality on a superconducting quantum processor
Yousef Mafi, Ali G. Moghaddam, Teemu Ojanen
Combining recent advances in superconducting quantum hardware, we explore quantum correlations in a previously inaccessible regime by observing \emph{simultaneously} high-dimension…
