“…Two key high-risk / high-reward pioneering elements are the quantum engineered coherent concatenation of units and the multidirectional optical detection. [4,5] and tailored nanosystems [6,7] in self-assembled arrays of increasing complexity [8,9,10], integration into a device and novel hardware and matched compilers [11,12] will be delivered. Preliminary experimental demonstrations of the response of solutions and of engineered nanoarray films are available as is the validation of logic operation in parallel.…”

Quantum computation uses qubit in superposition and entanglement states providing more sophisticated computation ability regarding today's computers. For that purpose of developing a novel computer concept exploiting quantum dynamics at the nanoscale, we joined an EC H2020 program consortium named COPAC [1]. We propose to analyze the nonlinear 2 dimensional optical response of assembled nanostructures in solid arrays to a sequence of short laser pulses. Based on 2D maps of the stimulated emission we implement a novel paradigm for parallel information processing. Within the COPAC project, we, in KiloLambda, will develop the device nanostructure and engineering design.

“…The gate voltage variations are a strong perturbation on the system because the denominator in

can go through 0. As a result, there is no limitation by selection rules as is the case when a weak laser pulse is used to address a molecular system …”

To realize low‐power, compact logic circuits, one can explore parallel operation on single nanoscale devices. An added incentive is to use multivalued (as distinct from Boolean) logic. Here, we theoretically demonstrate that the computation of all the possible outputs of a multivariate, multivalued logic function can be implemented in parallel by electrical addressing of a molecule made up of three interacting dopant atoms embedded in Si. The electronic states of the dopant molecule are addressed by pulsing a gate voltage. By simulating the time evolution of the non stationary electronic density built by the gate voltage, we show that one can implement a molecular decision tree that provides in parallel all the outputs for all the inputs of the multivariate, multivalued logic function. The outputs are encoded in the populations and in the bond orders of the dopant molecule, which can be measured using an STM tip. We show that the implementation of the molecular logic tree is equivalent to a spectral function decomposition. The function that is evaluated can be field‐programmed by changing the time profile of the pulsed gate voltage.

“…[33][34][35] However, the processing and scaling of DNA computing systems are still challenging issues. Past efforts addressed these problems by designing reversible logic gates, 36,37 switching circuits, 38 continuous multivalued logic, 39 multiplexer-demultiplexer systems 40,41 and the construction of multilayer input-output logic gates. [42][43][44] Also, the use of twodimensional and three-dimensional DNA objects revealing shape complementarity or localized signal propagation could provide means to enhance computational efficacy.…”
