+  In the noisy intermediate scale quantum (NISQ) era of quantum computing the main factor limiting practical applications is the number of quality qubits available on a single quantum processing unit (QPU). For realising quantum utility, or even advantage on NISQ and future devices it can be useful to take a large quantum algorithm, cut it into smaller pieces and distribute the pieces on separate QPUs for execution in parallel. This would allow circumventing some of the hardware limitations, especially concerning the number of qubits on NISQ devices. Here, we use real hardware of the Finnish Quantum Computing Infrastructure (FiQCI) and simulations to demonstrate such a method, known as quantum circuit knitting.

+    As quantum computing continues to advance, the architecture of quantum processing units (QPUs) is becoming increasingly critical to the performance of quantum circuits, the backbone of all quantum algorithms. A key factor influencing the design of these circuits is qubit connectivity—how qubits are arranged and interact within a QPU. Different quantum platforms exhibit unique connectivity patterns that directly impact how quantum circuits are implemented and optimized.

+description: |-
+  What is dark matter? is a question that as been asked by scientists for many years. Recently an interest has spiked on using qubits as sensors for finding dark matter. Superconducting qubits are used for searching for a specific type of dark matter particle, an axion. Axions are light particles that do not interact with "ordinary" matter easily. However, they can cause additional electrical currents while coupling to photons which could be sensed by a qubit. These signals are very weak and it has been proposed that the sensitivity of the qubit sensor system could be increased with a quantum circuit. In this blog post, an introduction to the basics of using qubits as sensors and an introduction to axion dark matter is given. The use of superconducting qubits for axion dark matter detection is also motivated and the circuit for the sensitivity enhancement is presented. The code for this circuit is also available so that anyone can run it on the VTT Q50 quantum computer.
