You can rent it, but it's basically worthless at this stage.

  Is there anything you can do on a rented QC that you can't do cheaper on a simulated QC on a "classical" CPU/GPU today?
  • AlanYx 6mo ago
    No. They're a decent playground for prototyping hybrid algorithms but even that is limited. No one has yet published a hybrid algorithm on a rentable QC provider that has better benchmark performance than a modern CPU/GPU implementation.

    hello, yes ... especially if you want to execute quantum-circuits which use a lot of qubits. why!? one approach of the simulation of quantum-computers rely on the so called "state vector" of the machine, and its memory-usage grows exponentially. for example qiskit AER * https://qiskit.github.io/qiskit-aer/stubs/qiskit_aer.StatevectorSimulator.html# https://qiskit.github.io/qiskit-aer/stubs/qiskit_aer.Stateve... just as an example: for 32 qubits, the simulator needs 64 GB RAM =?> double the RAM for each additional qubit so: for 36 qubits, the simulator needs 1 TB RAM :) so it gets pretty "costly" to do simulations rather quickly ... just my 0.02€

  there's still a long road to commercial applications but today's hardware is simulating quantum systems beyond the scale of classical methods, for example [1]; an interesting line of work opposite to this can be found in those who improve classical methods towards such examples [2], but these are only developed because of the existing quantum hardware Really though, today's IBM hardware is good fun to play with, eg for generating moderately large GHZ states [1] https://arxiv.org/abs/2510.26845 https://arxiv.org/abs/2510.26845 [2]https://arxiv.org/abs/2306.14887 https://arxiv.org/abs/2306.14887
