Floating qubit
Web(If there are 64 qubits and only 22 CNOTs, not every qubit can be entangled with every other). The memory consumption can also depend on the simulation algorithm used. The most common is to store the quantum state as a vector of complex single precision floating point numbers and transform them based off the matrix form of the gate. WebSep 15, 2024 · However, for the floating merged-element transmon qubit (MET) with a symmetric layout Mamin2024 , where the island capacitance can be comparable to or even smaller than the coupling capacitance, the spurious channel can become the dominated microwave crosstalk source. In this situation, the magnitude of the spurious crosstalk can …
