Quantum technology

Quantum technology is an emerging field that brings together engineering and physics.

Exploiting the effects of quantum mechanics, quantum information technology (QIT) opens new possibilities in computing that exceed the capacity of conventional computing systems. While still at a nascent stage, QIT has attracted much attention from national governments as an area of critical research.

Quantum technologies already have a significant impact on the work of IEC technical committees in areas such as lasers and semiconductors. Technologies such as quantum computing and quantum sensing are on the rise, and present an exciting frontier for standardization, although their realized potential is still very much in its infancy.

The IEC and ISO have established a joint technical committee on quantum technologies, IEC/ISO JTC 3: Quantum technologies. The scope of this new IEC/ISO joint technical committee is to develop standards in the field of quantum technologies, including quantum computing, quantum simulation, quantum sources, quantum metrology, quantum detectors and quantum communications.

Quantum and superconductors

An important material used in quantum computing is superconductors. TC 90: Superconductivity and TC 3: Documentation, graphical symbols and representations of technical information have standardized symbols for fundamental elements of superconductor devices such as Josephson junctions, which are elements of quantum bits (qubits).

IEC 60617: Graphical symbols for diagrams includes commonly-used symbols for resistors, capacitors, transistors, etc. It now also includes the recently registered superconductor device for quantum technology.

Logic for superconductor devices

Example of the quantum symbols

S01924

S01924

Superconducting region,
one superconducting connection

S01925

S01925

Superconducting region, one superconducting connection and,
one normal conducting connection
(normal-superconducting boundary)

[画像:S01926]

S01926

Superconducting region, two superconducting connections with extremely small non-superconducting region(s)
(Josephson junction)

A Cooper pair cooper pair with magnetic dependence magnetic dependencesmakes sense for Josephson junctions. S00123: Magnetic field effect or dependence.

This IEC-60617 compatible circuit diagram depicts a transition-edge-sensor (TES) detector and a SQUID readout with Josephson junctions, magnetic effect, normal-superconducting boundaries in addition to conventional symbols such an inductor and resistors.

Note that the symbol symbol is obsolete.

IEC is offering these three symbols in high resolution free of charge to those working in universities and academic institutions.

We hereby confirm that we work actively in quantum physics and related domains at a University and wish to have access to the high-resolution graphic files for S01924, S01925, and S01926 for superconductor electronics, which rely on superconductor devices and Josephson junctions. We understand that these symbols are being made available to us by IEC free of charge for download. The end-user is permitted to store the files only on his/her own personal devices whose access is limited to his/her personal use. No local area network, wide area network, intranet or internet storage and access are permitted. The end-user may not lend, lease, reproduce, distribute or otherwise exploit, whether commercially or not, the files. For processing any of my provided personal data, I agree to IEC’s Privacy notice at https://www.iec.ch/privacy.
