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…
Spatial Engineering of Topological Quantum Matter with Structured Light
Matias Mustonen, Ali G. Moghaddam, Teemu Ojanen +1
Structured light provides a powerful means of controlling matter while itself exhibiting nontrivial spatial topology. Here, we show that these spatial structures can be harnessed t…
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…
Entanglement-limited linear response in fermionic systems
Hadi Cheraghi, Ali G. Moghaddam, Teemu Ojanen
We propose a general connection between entanglement-entropy scaling laws and the linear response functions of particle-conserving fermionic systems in their ground state. Specific…
General many-body entanglement swapping protocol: opportunities for distributed quantum computing
Santeri Huhtanen, Yousef Mafi, Ali G. Moghaddam +1
Sharing entangled pairs between non-signaling parties via entanglement swapping constitutes a striking demonstration of the nonlocality of quantum mechanics and a crucial building…
Entanglement entropy scaling laws from fluctuations of non-conserved quantities
Szczepan Głodzik, Kim Pöyhönen, Ali G. Moghaddam +1
Entanglement patterns reveal essential information on many-body states and provide a way to classify quantum phases of matter. However, experimental studies of many-body entangleme…
Noise resilience in adaptive and symmetric monitored quantum circuits
Moein N. Ivaki, Teemu Ojanen, Ali G. Moghaddam
Monitored quantum circuits offer great perspectives for exploring the interplay of quantum information and complex quantum dynamics. These systems could realize the extensively stu…
Exact solutions for topological surface states of three-dimensional lattice models
Matias Mustonen, Teemu Ojanen, Ali G. Moghaddam
In this work, we employ a generalized transfer matrix method that provides exact analytical and numerical solutions for lattice versions of topological models with surface terminat…
Postselection-free approach to monitored quantum dynamics and entanglement phase transitions
Kim Pöyhönen, Ali G. Moghaddam, Moein N. Ivaki +1
Measurement-induced entanglement phase transitions in monitored quantum circuits have stimulated activity in a diverse research community. However, the study of measurement-induced…
