After the decoding operation,the ions are spatially separated(see Fig.2c),and a measurement of the state of the ancillae is performed. Figure 1 Quantum circuit for the quantum error-correction protocol described and implemented in this work as one would compose it of single-bit rotations, Hada...
quantum error correction, and is thus less severe for fault-tolerance31. Nevertheless, it is always desirable to achieve and to verify lower crosstalk errors to save the overhead for large-scale quantum error correction. As for the entanglement fidelity of the communication qubit, our current ...
The exact crossover boundary is sensitive to platform-specific details such as gate times and control capabilities; given the large spread in gate timescales (≳3 orders of magnitude) across present-day platforms49,50, and uncertain overheads from quantum error correction or mitigation, we avoid ...
This allows us to measure the fidelity of a controlled-not logic gate and to experimentally investigate the error model for our computer. Based on the latter analysis, we test an important assumption underlying nearly all models of quantum error correction, the independence of errors on different ...

At the same time, the partners will also conduct basic verification experiments, such as quantum error detection, to identify issues and improve technologies for realizing quantum error correction. ...
Controlled quantum teleportation involves a third party as a controller for the teleportation of state. Here, we present the novel protocols for controlling teleportation of the arbitrary two-qubit and three-qubit states through five-qubit and seven-qubit cluster states respectively. In these schemes,...
We present the frequency stability performances of a vapor cell Rb clock based on the pulsed optically pumping (POP) technique. The clock has been developed in the frame of a collaboration between INRIM and Leonardo SpA, aiming to realize a space-qualifi
