Demonstration of Controlled-Phase Gates between Two Error-Correctable Photonic Qubits
Yuan Xu, Yuwei Ma, Weizhou Cai +11
To realize fault-tolerant quantum computing, it is necessary to store quantum information in logical qubits with error correction functions, realized by distributing a logical stat…
Perfect quantum state transfer in a superconducting qubit chain with parametrically tunable couplings
X. Li, Y. Ma, J. Han +8
Faithfully transferring the quantum state is essential for quantum information processing. Here we demonstrate a fast (in 84 ns) and high-fidelity (99.2%) transfer of arbitrary qua…
