Fields of innovation

Quantum Technologies

A leap into the future of engineering

Quantum technologies is a new field of engineering that translates the effects of quantum physics into practical applications with disruptive potential. By controlling single quantum entities and utilizing their characteristics, quantum technologies in the areas of sensing, computation and cryptography can realize future technologies.

Quantum Technologies

Engineering tomorrow

Quantum technologies unlock a world of engineering possibilities. These transformational technologies are poised to contend with the world’s most pressing trends such as urbanization, climate change and demography. Bosch is committed to engage in three areas that have the potential to effect lasting change.

Quantum sensors will significantly improve future sensors and will be key to maintaining Bosch’s world-market leadership in miniaturized sensor products.

Quantum computers and algorithms will enable Bosch to create completely new products and services and open up totally new possibilities in engineering.

Quantum cryptography, and in particular quantum random number generators, will transform security in the Internet of Things.

Quantum sensing

Quantum sensors form a new class of sensors with disruptive advantages in sensitivity, measurement range, and robustness. For example, innovative magnetometers in development using diamond quantum sensors could lead to new human brain machine interfaces. New quantum gyroscopes utilize nuclear magnetic resonance effects in atomic vapors. These quantum gyroscopes are a hundred times more drift stable than those currently available. They will allow fully inertial navigation and improved safety in highly autonomous driving.

A classical computation is like a solo voice – one line of pure tones succeeding each other. A quantum computation is like a symphony – many lines of tones interfering with each other.

Quantum computing and quantum simulation

We use a quantum computer to solve Schrödinger’s equation, calculating properties of materials or molecules in a materials simulation with quantum chemistry. This will allow us to develop new and improved functional materials, e.g. for energy storage, advanced sensors, and functional coatings.

Quantum computing can also solve optimization problems, which are fundamental in many engineering tasks as well as in logistics (e.g. traffic routing optimization), scheduling, and more.

Quantum computing will open new and unexpected possibilities for Artificial Intelligence. They will significantly speed up processing resulting in reduced time and sample complexities as well as better generalization ability.

Modelling a relatively basic molecule such as caffeine would require a traditional computer with 10 to the power of 48 bits, which is a number as large as about 10% of the amount of atoms in our planet, while a quantum computer would need just about 160 quantum bits (qubits).

Quantum cryptography

Quantum cryptography comprises quantum key distribution (QKD) and quantum random number generation (QRNG). With QKD, two parties establish a common secret key, which is the basis for secure communication. Random numbers are needed for encrypted communication and can be used to improve the security of communication networks or the Internet of Things. In the development of QRNG systems, we explore various quantum effects whose objective randomness is guaranteed by physics.

Partners in innovation

We pursue an open innovation strategy through engagement in various publicly funded projects together with leading academic experts in the context of the European Quantum Flagship program and the national quantum initiative QUTEGA.

Summary

Bosch is investing in the most promising technologies of tomorrow. The disruptive potential of quantum technologies will transform sensors, computers and security as we know them.
