Quantum

Revolutionary quantum signals will be transmitted across the network thanks to more accurate quantum hardware built using compound semiconductors. 

Securing the telecoms network of the future with quantum technologies

Quantum technologies harness the laws of quantum mechanics to perform tasks and solve problems that are far too complex for standard computers.

Quantum computing will revolutionise industry by exponentially increasing computational power, enabling breakthroughs in cryptography, drug discovery and materials science. 

Quantum technologies will allow data to be encrypted and decrypted in new ways, enabling extremely secure communications that are safeguarded against cyber threats.  

Quantum sensing and imaging technologies provide unprecedented levels of precision in measurement and imaging, with applications ranging from medical diagnostics to environmental monitoring and defence. 

Compound semiconductors are being used to build more accurate quantum hardware and repeaters. This will enable and enhance the transmission of quantum signals over the telecoms network. 

Compound semiconductors such as gallium arsenide (GaAs), indium phosphide (InP) and gallium nitride (GaN) have excellent electron mobility and optical properties, making them well-suited for a range of quantum applications. 

Key technologies

Quantum dots

Compound semiconductors such as indium arsenide (InAs) and gallium arsenide (GaAs) are used to build quantum dots — nanoscale structures that can trap and control individual electrons, allowing for the precise control and manipulation required for quantum computation.

SPADs

Single photon detectors (SPADs) are devices that can detect individual particles of light, called photons. SPADs built with compound semiconductors such as gallium arsenide (GaAs) and indium phosphide (InP) can detect tiny amounts of light, which is crucial for many quantum applications.

  • Speed
  • Security

Quantum hardware built using compound semiconductors will enable quantum computers to solve complex problems at unprecedented speeds, promising to revolutionise industries and accelerate innovation in the digital age. 

Compound semiconductors will be used to develop quantum technology capable of safeguarding sensitive information, protecting critical infrastructure and ensuring privacy in an increasingly interconnected and digital world.
