Developing Hamiltonian models for quantum processors with many qubits on the same chip
is crucial for advancing quantum computing technologies. Stray couplings between qubits …

While all quantum algorithms can be expressed in terms of single-qubit and two-qubit gates,
more expressive gate sets can help reduce the algorithmic depth. This is important in the …

As systems for quantum computing keep growing in size and number of qubits, challenges
in scaling the control capabilities are becoming increasingly relevant. Efficient schemes to …

We propose a theoretical scheme of using two fixed-frequency resonator couplers to tune
the interaction between two Xmon qubits. The indirect interaction between two qubits …

We conduct a systematic study of quantum circuits composed of multiple-control Z-rotation
(mczr) gates as primitives, since they are widely used components in quantum algorithms …
