Researchers achieve calculation of Jones polynomial based on Majorana zero modes

Experimental setup. (a) A conventional quantum cooling circuit consists of two Hadamard gates (𝐻), a local phase gate (𝑅), and a controlled unitary gate (𝑈). Here, a cnot gate (marked with a red dashed line) is newly introduced to realize non-dissipative imaginary time evolution (ITE) during the braiding motions 𝜎1 and 𝜎−12, and a Sagnac interferometer ( SI) has been…
