Apr 18, 2024 · A year ago, I registered in the IBM Quantum Computing app, which provides access to quantum computers and to simulators. I got an API key, and was able to run some programs. However, lately, I try to log in in my account and the system answers me with the same page, and I am not able to get another/the same API key.

Jan 11, 2022 · # do pip install qiskit-ibm-runtime first from qiskit_ibm_runtime import QiskitRuntimeService service = QiskitRuntimeService(channel="ibm_quantum", token="<MY_IBM_QUANTUM_TOKEN>") or, optionally use the save_account() method to save your credentials for easy access later on, before initializing the service.

Apr 29, 2020 · IBM Quantum Experience, the widest known and largest platform for small quantum computing experiments. There are various physical backends containing upwards of 20 qubits for free users, and more for 'IBM Q partners'. The chips have varying qubit connectivity (architecture), which can be of vital importance to low-level experiments.

Jan 5, 2020 · While the URL of the API actually changed, it looks like all methods have remained the same. You can find a list of such methods in Practical Quantum Computing for Developers by Vladimir Silva, starting at page 101.

May 22, 2021 · But now IBM has changed the interface of its platform, and I can't figure out where to get the API token for developers (while the API token for Qiskit is in the most prominent place). I would also like to see an example of using the API in action in Java. Example of a program that sends a schema to IBM Quantum and gets the result.

Feb 28, 2024 · Here is an example of a bell state simulated experiment for an ibm_brisbane backend: from qiskit import QuantumCircuit, transpile from qiskit_aer import AerSimulator from qiskit_ibm_provider import IBMProvider # get backend provider = IBMProvider() backend = provider.backends(name="ibm_brisbane")[0] # create a bell circuit circuit = QuantumCircuit(2, …

Nov 17, 2024 · The Hello Quantum ios game developed by IBM has the X, Z, H and CZ gates manipulating a 2 qubit array (im not sure if array is the right word?). I want to know how I can represent the qubit states in ...

Dec 8, 2020 · This is quite an unpractical hypothesis for real quantum computation. k-locality is a common criterion for a quantum computer and the only quantum computer I know of that has full qubit-connectivity is this one(I omitted the trivial cases of single- or two-qubit quantum computer). In the case of quantum devices that IBM provides via cloud ...

Jan 8, 2021 · Note that IBM uses superconducting transmon qubit rather than trapped ions qubits. When you design a quantum circuit, you don't usually don't think about the specific hardware specifications. That is, you would rather put your focus on designing a circuit to do the task at hand rather than thinking about what the qubit layout is on the QPU and ...
