Project description
Making quantum computing networks more resilient to noise
Preserving coherence is vital to the development of quantum computer networks. Qubits are delicate entities that must be kept carefully isolated from the external environment. If not, the qubit’s fragile superposition will decohere into a traditional computing state (a one or a zero). Decoherence also degrades entanglement between two or more qubits. The ERC-funded QOMUNE project will leverage multidimensional quantum states (qudits) that are more resilient to external noise. Able to encode several numbers instead of ones and zeroes, qudit computers are more efficient in solving complicated problems than qubit computers. QOMUNE envisages an innovative scheme for qudit generation and transmission and quantum interference.
Objective
Quantum Internet will allow unprecedented applications that will dramatically change our lives, spanning from quantum secured communications to distributed quantum simulations, i.e. ultra-precise clock synchronisation, quantum secured identification, efficient distribution of data and energy, quantum sensors and secure access to quantum devices in the cloud. The main technical limitations currently restricting the range of applicability of the quantum internet are the intrinsic rate-distance limit and the extremely difficult coexistence with the present classical telecommunication infrastructure. Present quantum communication systems mainly use a two-dimensional encoding scheme (qubit) as information unit, which is very fragile and susceptible to external noise. In fact, due to decoherence processes, caused by the interaction with the external environment, the ability of the adopted qubits to remain in superposition and/or in an entangled state is severely jeopardised. On the contrary, by adopting multidimensional quantum states (qudit), which are by nature more robust to noise owing to their higher information efficiency, the potential to realise the quantum internet is within our grasp. QOMUNE intends to build and test the constituents for a Quantum Internet based on multidimensional quantum states, by combining new technological advances with unconventional quantum interference. QOMUNE envisages a novel scheme for the generation, transmission and interference of qudits, which are fundamental actions of a quantum network. Photonic integrated quantum sources combined with multicore deployed fibres and pioneering design of efficient and scalable multidimensional quantum interference will be adopted for the realisation of QOMUNE building blocks. QOMUNEs objectives and results will redefine the state-of-the-art of Quantum Internet in terms of tolerance to noise in a realistic scenario and coexistence with the worldwide telecommunication infrastructure.
