Quantum 9, 1776 (2025). https://doi.org/10.22331/q-2025-06-18-1776 Despite significant advances in quantum algorithms, quantum programs in practice are often expressed at the circuit level, forgoing helpful structural abstractions common to their classical counterparts. Consequently, as many quantum […]

Quantum 9, 1770 (2025). https://doi.org/10.22331/q-2025-06-17-1770 We propose a novel quantum algorithm for solving linear autonomous ordinary differential equations (ODEs) using the Padé approximation. For linear autonomous ODEs, the discretized solution can be represented by a […]
Quantum 9, 1769 (2025). https://doi.org/10.22331/q-2025-06-12-1769 Gaussian states of bosonic quantum systems enjoy numerous technological applications and are ubiquitous in nature. Their significance lies in their simplicity, which in turn rests on the fact that they […]
Quantum 9, 1768 (2025). https://doi.org/10.22331/q-2025-06-12-1768 We show that using qutrits rather than qubits leads to a substantial reduction in the overhead cost associated with an approach to fault-tolerant quantum computing known as magic state distillation. […]
Quantum 9, 1767 (2025). https://doi.org/10.22331/q-2025-06-12-1767 Logical qubits can be protected against environmental noise by encoding them into a highly entangled state of many physical qubits and actively intervening in the dynamics with stabilizer measurements. In […]
