New pre-print “Quantum Tensor Product Decomposition from Choi State Tomography”
In our new pre-print, we study the entangling features of a unitary quantum operation using its operator-Schmidt, or tensor product decomposition. We present an algorithm for unbalanced partitions into a small subsystem and a large one (the environment) that computes the tensor product decomposition of a unitary whose effect on the small subsystem is captured […]

New Pre-Print “Highly Efficient Encoding for Job-Shop Scheduling Problems and its Application on Quantum Computers”
Combinatorial optimization problems are regarded as a promising use case for quantum computing. One such problem, which is of paramount relevance in industry, computation, and economics, is (flexible) job shop scheduling. It considers a set of jobs of varying processing times and seeks to schedule them on a set of machines and/or operators with varying […]

New Pre-Print “Designing Fast Quantum Gates with Tunable Couplers: A Reinforcement Learning Approach”
Achieving fast and high-fidelity two-qubit entangling gates is crucial for future fault-tolerant error-correcting codes in scalable systems as well as for efficient implementation of quantum algorithms in current noisy devices. Our preprint (https://arxiv.org/abs/2312.16358) presents an advancement in quantum computing, leveraging reinforcement learning (RL) to rapidly generate two-qubit gates in superconducting qubits, achieving an unprecedented 11 […]Achieving fast and high-fidelity two-qubit entangling gates is crucial for future fault-tolerant error-correcting codes in scalable systems as well as for efficient implementation of quantum algorithms in current noisy devices.

New Paper “Tunable coupler to fully decouple and maximally localize superconducting qubits” Published in Physical Review Applied
We are happy to announce that our paper “Tunable coupler to fully decouple and maximally localize superconducting qubits” has been published in Physical Review Applied. In our paper, we derive conditions for tunable couplers to suppress all parasitic interactions, i.e. state delocalization and ZZ-crosstalk simultaneously. This is a desirable property, as the fidelity of 2-qubit […]

New Paper “Problem Specific Classical Optimization of Hamiltonian Simulation” published in Physical Review Research
We are glad to announce that our paper on “Problem Specific Classical Optimization of Hamiltonian Simulation” has been published in Physical Review Research. In our paper, we introduce a variational algorithm for Hamiltonian simulation. As quantum optimization faces fundamental problem when performed on a quantum machine, we studied optimization on a classical computer. As opposed […]

Tunable coupler to fully decouple superconducting qubits
A major bottleneck of current NISQ hardware is low fidelity of 2 qubit gates. A component to improve this is the possibility to completely switch off interactions between qubits. In our pre-print we derive conditions for the coupler to suppress all parasitic interactions, i.e. state delocalization and ZZ-crosstalk. We then develop a coupler model for […]
