Glossary: Quantum Computing

Quantum Computing (QC): Uses the principles of quantum mechanics (e.g., superposition, entanglement, and interference) for computation and uses quantum bits (Qubits) instead of classical bits.

Qubit: A Qubit is the smallest computational and information unit of a quantum computer and can assume the states 0 and 1 simultaneously. Only when measured does it commit to a specific state. Quantum computers achieve great computing power with just a few qubits. With each Qubit, the computing power doubles (ideal model).

Superposition: A qubit can be kept in a state of superposition, which is a combination of all possible configurations of the qubit. Groups of qubits in a superposition can create complex, multi-dimensional computational spaces.

Entanglement: Entanglement is a quantum mechanical effect. When two qubits are entangled, changes to one qubit directly affect the other qubit. Quantum algorithms use these relationships to find solutions to complex problems.

Quantum volume: Measure of quality and performance (stability of qubits, controllability, robustness, computational errors) for each individual quantum computer (introduced by IBM).

Quantum superiority: Proof that quantum computers can solve certain problems faster than classical supercomputers. Has only been demonstrated for very specific tasks (e.g., by Google in 2019).

ParTec AG Modular Super and Quantum Computing

ParTec AG specializes in the development and manufacture of modular High-Performance Computing (HPC) systems and Quantum Computers (QC) as well as accompanying system software. Its offering also includes consulting and support services in all areas of the development, construction, and operation of these advanced systems. The dynamic Modular System Architecture (dMSA) paradigm is the result of more than ten years of research and has been developed by ParTec as a novel system design for massively parallel high-computing systems. The dMSA and its enabling ParaStation Modulo Software Suite, developed and maintained by ParTec, have proven particularly successful for the complex requirements of massive computing power in AI. Further information on the company and ParTec AG’s innovative solutions in the field of high-performance computing and quantum computing can be found at www.par-tec.com.
