Over the past decades, new physical effects have been applied to the construction of standards: the Josephson
quantum effect, the quantum Hall effect, the Meissner effect, the Mossbauer effect, and others. and Hall. The
development of quantum Josephson circuits has created high hopes for reliable processing of quantum information.
Despite the fact that this progress has already led to various experiments proving the principle of operation on
small quantum systems, a large scale step is required for protocols with many qubits. Fail-safe calculations with
protected logical qubits are usually carried out at the expense of significant hardware costs. Each of the physical
qubits involved must still satisfy the best achieved properties (coherence times, coupling forces and tunability).
Here and in order to consider alternative approaches to overcoming these obstacles, a number of recent experimental
developments following these proposals are being considered in order to create a new hardware – efficient paradigm
for the protection of quantum memory and universal quantum computing.
