What is Quantum Computing?

Quantum Computers are devices that perform quantum computations, this emerging technology seeks to use the properties of quantum states including superposition, interference, and entanglement to harness the unique behaviour of quantum physics and applying it to computing.

All the computers that are a part of our day to day life use bits to operate and preform tasks, however a quantum computer uses qubits (CUE-bits) to run multidimensional quantum algorithms.

Why do we need it?

Quantum computer researchers are working to understand what problems this new technology would be most suited for, however it is believed that it could be useful in a vast array of fields including defense, finance, medical, telecommunications and even Ai systems development.

Quantum computing will likely propel our current computing capabilities far beyond what conventional computing could ever achieve. It is expected that quantum computers will be able to calculate and analyse all types of data in minutes, however this advanced technology comes with more than a few challenges and obstacles that must be solved in order to achieve the end result.

The Issue of Scalability

Each qubit can need as many as 3 Arbitrary Waveform Generators (AWG) in order to control, this is will most likely increase in future as researchers work with more qubits. Scalability and cost will likely become a vital consideration when researching quantum computing and working with these qubits.

High Fidelity & Precise Signal Sources

A challenge of quantum computing researchers is the need to have very particular signals that are required to fully understand how the qubits behave. It is incredibly important that researchers have a controlled signal otherwise this could seriously effect the project, having this controlled precision signal will enable smooth test set ups and waveforms. MCS Test offer a range products from multiple manufacturers which offer signal fidelity coupled with class-leading sample rate and memory depth, giving you the industry's best signal stimulus solution.

High speed digitizers are instruments that capture fast-changing electrical signals using analog-to-digital converters (ADC) and store digitized waveform data in fast memory. They are often multi-channel instruments to enable comparison of signals. In these respects they are similar to digital oscilloscopes, however digitizers may measure over a narrow range or include adjustable amplifiers to support wide signal ranges
