The company IonQ announced the creation of a nearly ideal architecture of a quantum computer. It is based on the use of ions and shows so high a precision and reliability that physics problems now fade into the background. Developers is to focus on improving ON and preparing to create a commercial version of a supercomputer.
In quantum computers from IBM or Intel qubits, quantum bits, performed on superconductors and their easy integration into standard electronic circuits. Quantum computer company IonQ uses a magnetic trap to hold ions of ytterbium in a vacuum. Manage use laser beams such qubits was much more stable and more reliable than others. In particular, the accuracy in single and double qubits made up of 99.97 % and 99.3% for the system with 79 qubits.
One of the main problems of quantum systems qubits subject to quantum confusion, and because over time, as participation in various operations, they dekoriruyut, losing stability. The more iterations, the more accumulated errors and lower the precision of the calculations. Developers ion computer failed to tie between an arbitrary pair of qubits, instead of having to pass data along the chain of qubits, thereby significantly reducing the number of operations. As a result, even after 50 operations, the qubit remained unchanged at 75%, which is very large by modern standards.
His achievement developers IonQ demonstrated with the calculation of the energy state of water molecules. This is a fairly simple task, but it requires many repetitive calculations that prior to quantum computers was a barrier. Ion model showed excellent results, indicating its high potential and opens up new avenues for development of quantum computing systems.
