Center of Excellence in Quantum Technologies

The project aims to develop quantum technology in India. It is a collaboration between the Indian Institute of Science (IISc), the Raman Research Institute (RRI), and the Centre for Development of Advanced Computing (C-DAC), Bengaluru.

Quantum Computer

IISc Objectives

At IISc, the project targets three main areas: (1) Quantum computation, (2) Quantum communication and networking, (3) Quantum algorithms, simulations and post-quantum cryptography. Central to the work in these areas is the setup of technical infrastructure as well as skill development and training.

Quantum Processor

Development of a 4-qubit superconducting quantum processor, with nanofabrication infrastructure and electronics for control and measurement.

Quantum Networks

On-chip quantum communication devices with integrated photonics. Demonstration of fiber based QKD at laboratory distances.

Quantum Communication

Development of Graphene based number resolved single photon detector and heralded single photon sources.

Theoretical Efforts

Quantum algorithms, quantum simulator incorporating noisy gates, QKD protocols and post-quantum cryptography.

RRI Objectives

The long-term objective of the project is to lay a solid foundation for the field of Quantum Technology in India. In the first phase spanning two years, our emphasis will be on developing necessary elementary hardware components, reliably and indigenously. Together with that, the project will develop technical and manpower skills in the field to such an extent that in the next phase.

Genuine random number generation

Novel schemes of generating genuine random numbers using fundamental physical principles and inherent unpredictability of natural phenomena. The target is to get close to 2 bits of genuine randomness per entangled photon pair, with Mbit/s generation rate.

Quantum Interactions

Design of physical ion trap modules and precision diode laser mount modules, with multipurpose digital operation, control and measurement.

Quantum Key Distribution

Utilization of such randomness in quantum key distribution. Higher dimensional quantum key distribution using novel spatial degree of freedom of photons. Preliminary experimental developments towards quantum teleportation
over a long fiber link up to 100km.

Quantum Sensing

Demonstration of a precision magnetic field sensor (< 10 nano-Tesla sensitivity), using spin correlation spectroscopy of cold atoms.

C-DAC Objectives

At C-DAC, the project targets: (1) FPGA based system to interface with quantum processors, and (2) Python based software interface for the quantum measurement hardware.

Control hardware and software for quantum devices

Xilinx Ultrascale+ architecture-based control electronics for superconducting qubit-based quantum processor. Basedband and microwave arbitrary waveform generator.

Custom IP, SDK and Embedded Linux development

Development of custom IP, SDK, and embedded Linux application to receive different signal parameters over Serial/Ethernet and to transmit acquired data to a remote user.

Python Interface

Python interface, over Serial/Ethernet, for control electronics to generate arbitrary waveform and data acquisition. SCPI-based User Interface for lab instruments. 

Data acquisition system

Implementation of an AXI-DMA based internal/external triggered data acquisition system for based band and microwave signals
