Trade-off relations between two-qubit coherence and intrinsic concurrence for Heisenberg XYZ states induced by intrinsic decoherence model by Fahad Aljuaydi

“…This work investigates the trade-off relations between intrinsic concurrence, concurrence, first-order coherence, and total purity for generated two-qubit Heisenberg XYZ states due to spin–spin interactions supported by spin–orbit interactions in the x and y directions with an external inhomogeneous magnetic field in the x direction by using the Milburn model of intrinsic decoherence. …”

A mid-circuit erasure check on a dual-rail cavity qubit using the joint-photon number-splitting regime of circuit QED by Stijn J. de Graaf, Sophia H. Xue, Benjamin J. Chapman, James D. Teoh, Takahiro Tsunoda, Patrick Winkel, John W. O. Garmon, Kathleen M. Chang, Luigi Frunzio, Shruti Puri, Robert J. Schoelkopf

“…This ‘joint-photon number-splitting’ regime extends single-oscillator techniques to two-oscillator control, which we use to realize a hardware-efficient erasure check for a dual-rail qubit encoded in two superconducting cavities. This scheme leverages the high-fidelity beamsplitter coupling already required for single- and two-qubit gates while permitting minimal crosstalk between circuit elements. …”
