Minimum Toffoli depth for the multi-controlled Toffoli gate via teleportation
Spyros Tserkis, Muhammad Umer, Eleftherios Mastorakis +1
The decomposition of complex quantum operations into experimentally feasible gate sets has been a central challenge since the early development of quantum computing. The multi-cont…
Depth optimization of CNOT ladder circuits
Spyros Tserkis, Muhammad Umer, Dimitris G. Angelakis
The increasing depth of quantum circuits presents a major limitation for the execution of quantum algorithms, as the limited coherence time of physical qubits leads to noise that m…
Information back-flow in quantum non-Markovian dynamics and its connection to teleportation
Spyros Tserkis, Kade Head-Marsden, Prineha Narang
A quantum process is called non-Markovian when memory effects take place during its evolution. Quantum non-Markovianity is a phenomenon typically associated with the information ba…
Quantifying total correlations in quantum systems through the Pearson correlation coefficient
Spyros Tserkis, Syed M. Assad, Ping Koy Lam +1
Conventionally the total correlations within a quantum system are quantified through distance-based expressions such as the relative entropy or the square-norm. Those expressions i…
