Strengthening quantum research efforts

Quantum technology applications

Quantum effects are already part of our everyday lives. Modern smartphones, for instance, contain billions of transistors, which rely on the quantum mechanical properties of semiconductors to control currents and voltages. This is the first generation of quantum technology and involves harnessing natural quantum effects. The second generation, on the other hand, focuses on creating and controlling individual quantum states.

Our strong expertise in RF technology and the outstanding performance of our devices support the advancement of quantum research. In July 2021, we also welcomed Zurich Instruments to the Rohde & Schwarz family. Zurich Instruments provides a wide range of quantum technology solutions that are the ideal addition to the Rohde & Schwarz T&M portfolio.

The three key areas of quantum technology are:

  • Quantum computing
  • Quantum communications
  • Quantum sensor technology

Quantum computing is an especially vital area of quantum technology. Unlike conventional systems that process data sequentially using binary code, quantum computers (QC) save time by processing data in parallel. This allows them to handle complex problems that are difficult for conventional computers. QCs could make public key encryption methods obsolete, necessitating research on possible future attack scenarios.

This is where quantum communications come in. Quantum key distribution (QKD) is a cryptographic technique that enables two parties to securely exchange a secret encryption key over a public channel. Any attempt to eavesdrop disturbs the quantum state and alerts the communicating parties. Unlike quantum computing, QKD is very close to being realized. Rohde & Schwarz and Zurich Instruments are actively involved in this process, participating in projects such as OpenQKD to integrate quantum-safe solutions into existing systems.

Sensing is another important application of quantum technology. Quantum sensing has great potential for high-precision radar, which can detect small, slow-moving objects such as drones - a task conventional radar technology struggles with. Rohde & Schwarz has supported the UK Quantum Technology Hub Sensors and Timing project in assessing quantum clocks for this exact purpose. We are also involved in the Quarate (Quantum Radar Team) project to explore quantum radar at microwave frequencies.

Supporting quantum computing research

Although quantum computing technology is still in the experimental stage, it is evolving rapidly, and many exciting applications are on the horizon. For example, simulating complex molecules is extremely challenging with current computers, requiring over a century of processing time. A quantum computer, on the other hand, could theoretically accomplish such a task within a matter of hours. Quantum computing is also expected to benefit numerous other applications, such as climate analysis, transportation planning, bioinformatics, financial services, encryption and codebreaking

Together, we are proud to be the trusted partner of many quantum research projects and organizations: OpenSuperQPlus, MUNIQC-SC, IQM, Q-NEXT, Chicago Quantum Exchange (CQE) and ETH Zurich, among others. Through these collaborations, we continue to drive advancements in quantum computing research and play an integral role in shaping the future of this transformative technology.

Master your quantum testing challenges

Building and running a quantum computer comes with many complex challenges, and these challenges are magnified as the number of qubits increase.

Key challenges when testing quantum systems include:

  • Characterizing fabrication processes and testing new materials using spectroscopy to increase the coherence time of the qubits
  • Verifying functionality and characterizing quantum computing control and readout system
  • Ramping up the quantum processor
  • Keeping the coherence of the system stable at low error rates
  • Potential loss of quantum information introduced by unstable noisy qubit control pulses
  • Automated run of quantum algorithms with a highly integrated, scalable control system
