Again, these are small baby steps, but they are also important.Spain has completed the first phase of installing its first national quantum computer. The project is implemented by the Qilimanjaro-GMV consortium and the first quantum computer is located in Barcelona. The quantum chip itself was made by startup QuantWare and has five qubits. It is now also available via the cloud to Spanish researchers. In total, this quantum center should host seven quantum computers, with the last one in expected to have qubits.
The quantum computers will then be closely linked to the supercomputer MareNostrum Chinese American Phone Number List for the purpose of hybrid computing.The first public quantum computer in SpainThe first public quantum computer in SpainAuthor IFAEQuantinuum announced the first chemical simulations on a quantum computer using logic qubits. Specifically, they simulated the hydrogen molecule H and calculated its ground state. Logical qubits generally increase the fidelity of quantum operations as well as coherence.

Here, the quantum circuit had two-qubit gates—a huge number on current machines. Another trick to save quantum resources is quantum error detection. In such a case, the calculation is discarded and started again (mostly the entire quantum circuit must be finished, if there are no measurements in the middle of the circuit). The H- processor was used for this simulation.Gero is an innovative startup that uses AI to
