# 3. Select a backend (a real quantum computer) # We select the least busy real quantum computer available backend = service.least_busy(operational=True, simulator=False)
# 1. Connect to IBM Quantum (you need an API token from your dashboard) # service = QiskitRuntimeService(channel="ibm_quantum", token="YOUR_API_KEY_HERE") # Ideally, save your account first so you don't need to paste the token: # QiskitRuntimeService.save_account(channel='ibm_quantum', token='YOUR_API_KEY_HERE', overwrite=True) free cloud based quantum services
# 2. Create a simple circuit (Bell State) qc = QuantumCircuit(2) qc.h(0) # Put qubit 0 in superposition qc.cx(0, 1) # Entangle qubit 0 and 1 qc.measure_all() # Measure the results Create a simple circuit (Bell State) qc =
Free access lowers the . Traditionally, quantum hardware cost millions to build and maintain. Cloud services allow a student in a remote area to run the same circuit as a researcher at a top-tier university. This open-access model accelerates innovation in fields like cryptography , material science , and drug discovery . Limitations to Consider Free tiers often come with constraints: This open-access model accelerates innovation in fields like

Google (Quantum AI) is famous for claiming "Quantum Supremacy," but their access model is different.
