Circuit centric quantum architecture design

Abstract

With the development in the field of quantum physics, several methods for building a quantum computer have emerged. These differ in qubit technologies, interaction topologies, and noise characteristics. In this article, insights are given into the circuitcentric architecture design of Noisy Intermediate-Scale Quantum (NISQ) devices. The dependence of the circuit size, circuit depth on the interaction and connection between different qubits present in quantum hardware are discussed. A noise-aware procedure is presented which helps in determining the optimal interactions between different qubits of a quantum chip to execute a given circuit in the most efficient way possible. In this article, the 5-qubit hardware in a noiseless setting is illustrated with an example. Also, a benchmark-driven analysis is performed to show the importance of noise adaptivity in determining the hardware reliability. It is concluded that a generalized and flexible procedure such as this approach can aid in determining the design of hardware accurately for which the circuit runs efficiently, that is, with the least number of clock cycles, the lowest gate operations, and noise-based errors.

Experimental Realization of Quantum Darwinism State on Quantum Computers

“…A python module named QISKit [13] is also introduced to write programs, for running the quantum circuits on real devices and to collect the results. A larger number of tasks have already been performed such as quantum simulation [14][15][16], quantum machine learning [17][18][19], quantum algorithms [20][21][22], quantum communication [23][24][25], quantum cryptography [26,27], quantum circuit architecture [28][29][30], quantum game [31,32] to name a few.…”
