WP# Workpackage title Beneficiary Work performed

We experimentally and theoreticallydemonstrated the purity (polarization) controlof qubits entangled with multiple spins, usinginduced dephasing in nuclear magneticresonance setups to simulate repeatedquantum measurements. We showed that onemay steer the qubit ensemble towards aquasiequilibrium state of a certain purity bychoosing suitable time intervals betweendephasing operations. We presented a directmeasurement of the bath-coupling spectrum inan ensemble of optically trapped ultra-coldatoms, by applying a spectrally narrow-bandcontrol field.

Brief description of the work performed duringthe period, addressed on Workpackage level.

Fluctuations exploration and control in JJ devices

The measured spectrum exhibits non-monotonic features due to the oscillatorymotion of the atoms in the trap. These featuresagree with our analytical models and numericalMonte Carlo simulations of the collisional bath.From the inferred bath-coupling spectrum, wepredicted the performance of some well-knowndynamical decoupling sequences. We thenapplied these sequences in experiment andcompared the results to predictions, findinggood agreement in the weak-coupling limit.

Phase dynamics has been investigated in differenttypes of high critical temperature superconductors(HTS) grain boundary (GB) Josephson junctions(JJs). Switching current probabilities measurementshave been realized down to 20 mK for differentjunction configurations with a variable orientation ofthe interface with respect to the electrodes. The GBforming the barrier changes as a function of theinterface orientation and determines different barriertransparency and levels of dissipation. Apart fromcanonical quantum and thermal regimes (T1.8), wehave found evidence of a tunable moderatelydamped regime.

Thermal fluctuations assist in premature switchingi t th i ti t t d th th h d h l iinto the resistive state and, on the other hand, help inretrapping back to the superconducting state. Theseprocesses are unavoidable in junctions characterizedby low values of the critical currents, and therefore inquantum superconducting electronics employingnanotechnologies. We have compared systemsbased on low critical temperature superconductors(LTS) JJs designed to be in a moderately dampedregime. These junctions employ NbN as asuperconductor and may present some advantageswith respect to Nb junctions for the realization ofsuperconducting qubits, because of possiblereluctance to form intrinsic two-level systems.

These junctions employ NbN as asuperconductor and may present someadvantages with respect to Nb junctions for therealization of superconducting qubits, becauseof possible reluctance to form intrinsic two-level systems. HTS JJs seem to offercomplementary functionalities when comparedto LTS systems and some more flexibility intuning the crossover temperature of the phasediffusion regime (D1.2). In addition phasediffusion both in LTS (results available inliterature) and HTS (our measurements) seemto enter into a freeze-out regime independentof temperature below a temperature thresholdin the range of hundred of mK.

qubit (T2.4). The system is basically a rf-SQUID(Superconducting QUantum InterferenceDevice), i.e. the “qubit’s” Josephson junctionwill be embedded in a superconducting loop,therefore forming a rf-SQUID. This way thebias can be executed by simply inductivelycoupling an on-chip superconductive coil tothe qubit.


21/11/201116:53

The dynamic of a rf-SQUID can be describedusing a double well potential, each wellcorresponding to a different magnetic fluxstate. The circuit is dimensioned on thejunction parameters obtained on submicronYBaCuO biepitaxial Josephson junctions. Thetwo flux states can be discriminated using adc-SQUID switching magnetometer alsointegrated on-chip and inductively coupled tothe qubit. (example of superconducting hybrid) to passin a second phase to an in-plane all-HTS read-out.

In the design we have taken advantage of theflexibility of low Tc superconductors toimplement the flux bias lines and the dc-SQUID read-out magnetometer. We havedesigned two read-out circuits. In a first stagewe will use Nb-based circuits in a flip chipconfiguration This approach iscomplementary to the trasmon design, whichis currently one of the focuses of the

Probably the most relevant is the fact that weare getting close to the ultimate limitconfiguration of a junction on basically a singlefacet. This responds to the ultimate aim is toproduce junctions, whose properties are solelythe result of their intrinsic nature and not theproduct of any artefact.

This responds to the ultimate aim is toproduce junctions, whose properties are solelythe result of their intrinsic nature and not theproduct of any artefact. We have producednanowires of width down to 50 nm operatingup to 80 K, and nano-rings with averageradius of 200 nm and arms of the same size.The study of flux dynamics in these structures

The study of flux dynamics in these structureshas provided important elements on effects ofsize quantization, on how noise enterssuperconducting interconnects, and to whatextent it is possible to prevent that. Incollaboration with Chalmers noise studieshave been extended to specific configurationsof biepitaxial junctions with basal plane grainboundary.

All this work cannot be disjointed from thework presented the the WP1, where switchingcurrent probabilities have been measured ondifferent types of HTS Josephson junctions.

We demonstrated that collective continuousvariables of two species of trapped ultracoldbosonic gases can be Einstein-Podolsky-Rosen-correlated (entangled) via inherent interactionsbetween the species. We proposed twodifferent schemes for creating thesecorrelations. We quantified the correlations by

using known measures of entanglement.

CEA has operated an hybrid structurecombining a superconducting qubit and a NVspin ensemble coupled through a resonator. Aspin based memory was demonstrated.

The progress achieved in the fabrication ofHTS nanostructures (D2.1) and thecomprehension of some transport modes hasallowed realizing the first generation of HTS –nanowire hybrid structures. Trenches from 50nm to 100 nm separate HTS electrodes andnanowires of size ranging from 60 to 100 nmwork as a diffusive barrier. Transportproperties have demonstrated the firstfunctionality of the devices. Up to nownanowires are of InAs, and the final structureis technologically quite demanding due to thestructural complexity of both components ofthe junctions.

The fabrication process can be applied to allsorts of barriers and hybrid structures, andCNR

We are now in conditions to provide HTS andHTS hybrid samples to MIDAS partners forexperiments on dynamical fluctuation control,once conditions to perform experiments onLTS JJs are settled. The only limit is the Qdissipation factor, that at the moment is notmuch higher than 10. We believe that higherQ values (and therefore lower levels ofdissipation) can be achieved for biepitaxialjunctions, when the GB width will be reducedto the size of a single facet (of the order of100-200 nm), the current limit for the width isabout 500 nm.

The promising preliminary results obtained on hybrid structures during the first twoyears have motivated CEA to build a new experiment fully dedicated to thisresearch.This investment and the manpower needed, supported by CEA and byMIDAS, explains the overspending.The research on transmon qubits for WP1 has been performed in parallel in an existing laboratory with little Midas support. Theresearch has continued during the third year with important results obtained.Three manuscripts acknowledging MIDAS have been submitted at PhysicalReview Letters

when the project were submitted, part of the personnel expenses (the grants, i.e. not proper employment contracts but temporary ones) did not generate overheads.CNR rules changed, so the inderect costs lifted. furthermore not all the men months were related to grants, as the budget foresaw, but a researcher was hired. and the relevant costs an OH lifted again.

Speciel Remarks

The budget utilization of 130% can be explained by the personal costs of all permanent researchers in MIDAS. This time has been larger than initially previewed for the following reasons:Wiebke GUICHARD: As last year she has only 66% of her normal teaching load, and therefore more time for research. She is promoted Professor with larger salary and therefore the personal costs are higher than initially previewed. The supplementary costs are payed by Institut Universitaire de France. Nevertheless all the time spent on MIDAS has been declared in the time sheets. Anna Minguzzi spent more time on project this year in order to finish PhD of G. Ferrini. Frank Hekking spent more time on project in order to finish calculations of finite size effects with postdoc G. Rastelli. These results will be published soon. The supplementary costs will be taken in charge by Université Joseph Fourier and CNRS.
