Activity summary

CEMES is developing quantum technology based on a dual approach using (1) single molecular design and atom manipulation on surfaces to create quantum circuits and logic gates and (2) plasmonic circuits and modal logic gates coupled to single photon sources (QIPC 4.2[1]). By a combined theoretical and experimental effort sustaining both approaches, CEMES aims at downsizing quantum information processing and communication to devices with footprint as small as 1 nm2 and interconnects as narrow as 1 nm, a formidable challenge for miniaturizing the mainstream QIPC paradigms (qubits or trapped atoms). Quantum control in a nanometer-scale single molecule or atom circuits is achieved by manipulating electronic quantum states by the presence of adatoms in order to implement quantum logic gates and, in the longer term, by using single molecule latching (QIPC 4.2, 4.3.1). Quantum computing is explored with magnetic molecular qubits but also with a range of qubit-free atomic-scale quantum systems using the new Quantum Hamiltonian Computing approach. With quantum plasmonics, optical qubits, namely colored centers in nanodiamonds, are coherently coupled through a delocalized quantum plasmonic mode sustained by crystalline plasmonic structures (QIPC 4.1.2-4.1.5). Such architectures are implemented to investigate and minimize the decoherence-dissipation link and allow the emergence of superposition states in an entanglement regime, which could be used for the design of single photon transistors and substrate-borne optical quantum logic gates. Both approaches offer ways to long range transfer quantum information and correlate quantum states through atomic-scale quantum channels such as molecular wires, atom wires or single plasmon waveguides (QIPC 4.1.2 - 4.1.5). The dual nature of plasmon modes (electron-photon) offers an opportunity to interface electronic and optical quantum computing and quantum information transfer devices. It also provides a way to reach larger bandwidth for the study of quantum dynamics. On the other hand, the quantum-classical and classical-quantum conversion is studied at the input and output of atom circuits or single molecule logic gates to exploit quantum decoherence instead of avoiding it (QIPC 4.3.4, 4.5). Finally, theory of the control and coherence of state space trajectory, complex logic gate design, zero effective mass tunneling, and quantum plasmonics description is carried out (QIPC 4.3).

we aim at developing devices and protocols to read out and process quantum information using individual molecular spins embedded in electronic circuits. To this end, prototypical hybrid nano-devices addressing single molecular spins will be designed and reliable methods for their realization will be developed. Core of such nano-architectures are magnetic molecules, specifically functionalized to graft electrodes, and exploited as spin (qu)bits.
