Compensated microwave driven qubits

A quantum processor comprising:

• a first qubit having a first driving frequency and a first microwave gate configured to apply a first microwave signal to the first qubit;
• a second qubit, adjacent the first qubit, having a second driving frequency, different from the first driving frequency, and a second microwave gate, separate from the first microwave gate, that is configured to apply a second microwave signal to the second qubit, wherein a respective driving frequency of each qubit is determined by a respective energy difference between different spin states of the qubit, and wherein the respective energy difference is determined by a respective magnetic field experienced by each one of the first qubit and the second qubit, respectively;
• and
• a controller configured to:
• apply a first electrical signal comprising the first driving frequency to the first microwave gate for applying the first microwave signal at the first driving frequency to the first qubit, for driving the first qubit;
• and
• simultaneously apply a second electrical signal to the second microwave gate, wherein the second electrical signal comprises the first driving frequency shifted in phase with respect to the first electrical signal for generating the second microwave signal with the first driving frequency arriving at the second qubit in counterphase to the first microwave signal for at least partially compensating crosstalk of the first microwave signal to the second qubit.
