13. Quantum Cascade (QC):
    • In semiconductor physics, “QC” can stand for “Quantum Cascade.” A quantum cascade is a type of semiconductor device used to generate and control quantum states in the flow of electrons, often employed in lasers and detectors operating in the infrared region.
14. Quality Cost (QC):
    • “QC” can also represent “Quality Cost.” This term refers to the financial costs associated with quality control measures, including inspections, testing, and process improvements, as well as the costs incurred due to product defects and warranty claims.
15. Quincy College (QC):
    • “QC” might denote “Quincy College,” which is an educational institution with campuses in Quincy and Plymouth, Massachusetts. Quincy College offers a range of academic programs and courses.
16. Quantum Computing (QC):
    • In the field of computer science and technology, “QC” can stand for “Quantum Computing.” Quantum computing is an emerging area of computing that leverages the principles of quantum mechanics to perform complex calculations exponentially faster than classical computers.
17. Quality Control Chart (QC):
    • In statistical process control, “QC” may represent “Quality Control Chart.” Quality control charts are graphical tools used to monitor and analyze variations in a process to maintain or improve its quality.
18. Quadrant Corporation (QC):
    • In business or corporate contexts, “QC” could refer to “Quadrant Corporation” or a similarly named company. This interpretation depends on the specific company or organization using the acronym “QC.”
19. Quilted Cover (QC):
    • In the bedding and furniture industry, “QC” might describe a “Quilted Cover.” This term refers to a protective and decorative covering for mattresses or furniture cushions, often made with quilted fabric.
20. Quality Checkpoint (QC):
    • In manufacturing and process control, “QC” can denote a “Quality Checkpoint.” This term describes a specific stage or location in a production process where quality inspections or tests are conducted to ensure product quality.
21. Quantum Computer (QC):
    • In quantum computing, “QC” specifically stands for “Quantum Computer.” A quantum computer is a type of computing device that leverages quantum bits (qubits) to perform computations with the potential to solve complex problems in fields such as cryptography and optimization.
