Errors in quantum processors are one of the largest bottlenecks to the commercially beneficial implementation of quantum applications. While many entities claim to push for more and more qubits, the more challenging aspect is to at least maintain, but ideally significantly improve the performance of the quantum gate operations.
For the implementation of quantum algorithms, trust into the device and its performance levels is adamant for any long-term commitment. This includes a both thorough as well as detailed description of the system capabilities. The users ought to be able to predict the performance for their particular use-case. In terms of quantum processor description, this entails details such as realizing Markovian dynamics (i.e. the order of gate operations has no affect on the achieved performance), stability of the system, negligible cross-talk between qubits, as well as a high connectivity. All of these aspects are addressed in our 19-inch rack-based quantum computer.
Furthermore, increasing the number of qubits should result in benefits for the end-user and gradually increase the performance levels. More qubits should mean more capabilities, building on top of previous achievements. We have repetitively shown to maintain system performance as we increase the number of qubits, demonstrating world-leading qubit entanglement, and implementing use-cases ranging from finance to chemistry – available at the stroke of a key via our cloud-access.
