Quantum 9, 1927 (2025). https://doi.org/10.22331/q-2025-12-02-1927 Recent advances in quantum computing have brought us closer to realizing the potential of this transformative technology. While significant strides have been made in quantum error correction, many challenges persist, […]
Quantum 9, 1926 (2025). https://doi.org/10.22331/q-2025-12-02-1926 Implementations of Roetteler’s shifted bent function algorithm have in recent years been used to test and benchmark both classical simulation algorithms and quantum hardware. These circuits have many favorable properties, […]
An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon emitted from a quantum […]
Quantum 9, 1925 (2025). https://doi.org/10.22331/q-2025-12-02-1925 Universal gate sets for quantum computation, when single and two qubit operations are accessible, include both Hermitian and non-Hermitian gates. Here we utilize the fact that any single-qubit operator may […]
Quantum 9, 1924 (2025). https://doi.org/10.22331/q-2025-12-02-1924 Digital quantum simulation (DQS) is one of the most promising paths for achieving first useful real-world applications for quantum processors. Yet even assuming rapid progress in device engineering and development […]
Quantum 9, 1923 (2025). https://doi.org/10.22331/q-2025-12-02-1923 Over the past decade, a number of quantum processes have been proposed which are logically consistent, yet feature a cyclic causal structure. However, there is no general formal method to […]
Quantum 9, 1922 (2025). https://doi.org/10.22331/q-2025-12-02-1922 Quantum random-access memory (QRAM) is a mechanism to access data (quantum or classical) based on addresses which are themselves a quantum state. QRAM has a long and controversial history, and […]
