npj Quantum Information volume 9, Article number: 84 (2023) Cite this article 5260 Accesses 4 Altmetric Metrics details Abstract Quantum photonic technologies, such as quantum key distribution, are already benefiting greatly from the rise of integrated photonics. However, the flexibility in design of...
Quantum error mitigation (QEM) presents a promising near-term approach to reducing errors when estimating expectation values in quantum computing. Here, we introduce QEM techniques tailored for quantum annealing, using zero-noise extrapolation (ZNE). We
We propose and analyze a universal method to obtain fast charging of a quantum battery by a driven charger system using controlled, pure dephasing of the charger. While the battery displays coherent underdamped oscillations of energy for weak charger dep
quantum memory, as the coherence time of qubits does not scale rapidly with the qubit numberNand does not heavily rely on quantum information propagation within the lattice. Hence, our main concern lies in the bounds of information propagation speed. Numerous quantum algorithms, such as the Harrow...
We develop a scalable, device non-specific, protocol for quantifying idle information loss by exploiting tools from quantum information theory. We implement this protocol in over 3500 experiments carried out across 4 months (Dec 2023–Mar 2024) on IBM’s entire Falcon 5.11 processor series. After...
The recent development of logical quantum processors marks a pivotal transition from the noisy intermediate-scale quantum (NISQ) era to the fault-tolerant quantum computing (FTQC) era. These devices have the potential to address classically challenging p
multiplied by a known factor. One can choose freely the angleτof the rotations entering the circuit, only modifying the multiplicative factor and not the precision of the result. It allows one to decrease the gate count at the cost of an increased number of shots on a quantum computer, yie...
