Quantum teleportation, the process of transmitting the state of a qubit in one quantum system to a qubit in a distant quantum system is an important area of research in quantum physics and quantum information science. The ability to transfer qubit states between different locations of a quantum computer could help in building scalable quantum processors which could solve highly complex problems. 

The quantum internet could rely on quantum teleportation for the transmission of quantum states across long distances enabling advances in areas such as secure communication and distributed quantum computing. Quantum teleportation is a primary component of quantum cryptography allowing the transmission of quantum information in a secure and tamper-free methodology.  

The practical implementation of quantum teleportation has substantial challenges for scientists and engineers. These challenges include improving the accuracy and efficiency of the process, developing suitable quantum memory and communication systems, and scaling up quantum teleportation for real-world applications. 

The teleportation protocol involves creating an entangled quantum state and sharing its two parts between the source and destination location. By controlling a laser beam impinging upon a certain type of crystal, two streams of photons can be created. Adjusting the laser and the polarization of the crystal, the photons can be transformed into a state of superposition and entanglement.   

Tabor’s Proteus Arbitrary Waveform Generators (ARBS) have up to 12 channels that can control phase and intensity of lasers used to energize the crystals which can split the laser beam into two streams of photons. Tabor Proteus ARBs have the unique ability to stream custom, multiple high-rate control signals to the laser. The Proteus ARBs have these unique capabilities for controlling quantum teleportation:  

  • Real time, continuous, and infinite waveform generation with real time data streaming 
  • 12 channels of 9 Gsample waveform memory with the ability to simultaneously download and generate waveforms with an 8 GHz output bandwidth. 

The Proteus series of instruments also includes the unique, new Arbitrary Waveform Transceiver (AWT) for transmission, and reception of RF signals with digital signal processing power. The Proteus AWT offers: 

  • Integration of both DAC and ADC signal generation and reception controlled by a signal FPGA for optimal synchronization and minimum latency to provide a high speed feedback loop allowing fast decision making 
  • Dual channel, 9 Gsample waveform memory with continuous and infinite waveform generation.
