Quantum Tunneling: From Theory to Error-Mitigated Quantum Simulation
Sorana Catrina, Alexandra Băicoianu
Ever since the discussions about a possible quantum computer arised, quantum simulations have been at the forefront of possible utilities and the task of quantum simulations is one…
Fast Swapping in a Quantum Multiplier Modelled as a Queuing Network
Evan E. Dobbs, Robert Basmadjian, Alexandru Paler +1
Predicting the optimum SWAP depth of a quantum circuit is useful because it informs the compiler about the amount of necessary optimization. Fast prediction methods will prove esse…
Fast quantum circuit simulation using hardware accelerated general purpose libraries
Oumarou Oumarou, Alexandru Paler, Robert Basmadjian
Quantum circuit simulators have a long tradition of exploiting massive hardware parallelism. Most of the times, parallelism has been supported by special purpose libraries tailored…
Halving the width of Toffoli based constant modular addition to n+3 qubits
Oumarou Oumarou, Alexandru Paler, Robert Basmadjian
We present an arithmetic circuit performing constant modular addition having depth of Toffoli gates and using a total of qubits. This is an improvement by a…
Parallelising the Queries in Bucket Brigade Quantum RAM
Alexandru Paler, Oumarou Oumarou, Robert Basmadjian
Quantum algorithms often use quantum RAMs (QRAM) for accessing information stored in a database-like manner. QRAMs have to be fast, resource efficient and fault-tolerant. The latte…
Synthesis of Arbitrary Quantum Circuits to Topological Assembly
Alexandru Paler, Simon J. Devitt, Austin G. Fowler
Given a quantum algorithm, it is highly nontrivial to devise an efficient sequence of physical gates implementing the algorithm on real hardware and incorporating topological quant…
