Crosstalk Insensitive Trapped-Ion Entanglement through Coupling Matrix Engineering (opens in new tab)

Author(s): Vikram Kashyap, Caleb Walton, and Sara MouradianOptical crosstalk due to imperfect addressing in trapped-ion entangling gates generates unwanted nonlocal entanglement between target ions and their combined set of neighbors that is difficult to mitigate using standard quantum error correction. We present a method to design entangling operations th…[Phys. Rev. Lett. 136, 253601] Published Tue Jun 23, 2026
