[Aspuru-Guzik Group List] Special ITAMP lunch seminar - Alicia Kollar, Princeton University (July 26th)

by Bekenstein, Rivka

*Special ITAMP Lunch Seminar* *Speaker: * Alicia Kollar (Princeton University) *Date:* Thursday, July 26th *Time:* 12:00-1:00 pm Includes Pizza. *Title: Hyperbolic and Flat-Band Lattices in Circuit QED* *Abstract: *The field of circuit QED has emerged as a rich platform for both quantum computation and quantum simulation. The unique deformability of coplanar waveguide (CPW) microwave resonators enables realization of artificial photonic materials with novel lattice structures. We will present two classes of such examples. First, we will show that these techniques can be used to produce periodic lattices in a hyperbolic space of constant negative curvature. Second, we present examples of Euclidean lattices which exhibit gapped flat bands. Because CPW resonators are one-dimensional objects, the lattices formed are naturally line graphs. We will show that line graphs lead naturally to flat bands and that criteria for when they are gapped can be derived from graph-theoretic techniques. The resulting gapped flat-band lattices are typically forbidden in standard atomic crystallography, but readily realizable in superconducting circuits. With the addition of high-kinetic-inductance materials or transmon qubits these systems will constitute a table-top simulator of interacting and quantum mechanical particles in strong curvature. *Location: *B-106 @ Center for Astrophysics (60 Garden Street) *Directions: *After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.

[Aspuru-Guzik Group List] Group meeting, Thu Jul 19, 3:30 PM, Div Room

by Ian Kivlichan

Hi all, Matthias will give our first group meeting from Toronto tomorrow! See below for his title and abstract. All the best, Ian ----------------- Title: Quantum error correction using mps and sdp Abstract: Error correction schemes are vitally important to the success of quantum computation. They try to remedy the loss of information and coherence that is inherent to current quantum computers. In this project I've combined previous research in the group (QVECTOR) with a competing technique using a semi-definite program (sdp). The result looks a lot like a matrix product state (mps) decomposition for qubit operations. I'll show benchmark results and the first results where all gates are noisy.

[Aspuru-Guzik Group List] [qip] talk on Monday

by Aram Harrow

*Speaker: *Carlo Ottaviani (University of York) *Time: *Monday, July 23rd 2018 4-5pm *Location: *Haus Room (36-428) *Title:* Measurement device independent quantum key distribution: from first design to high-rate modular network for quantum conferencing. *Abstract:* In continuous-variable (CV) measurement-device-independent (MDI) quantum key-distribution (QKD) each party sends modulated coherent state to an intermediate untrusted station (a relay) that, performing a Bell detection, establishes secret correlation between the parties, allowing them to share the secret-key. In this talk we review CV MDI-QKD, from the first design and experimental test toward the latest development. In particular, we discuss recent advancements about finite-size/composable security, the generalization to an arbitrary number of users arranged in a star-network configuration, and the design of a modular architecture based on star-network module. Our modular (*lego-like*) protocol resorts to a hybrid architecture where, once quantum-keys are generated for the users of each module, the shortest one can be propagated to all others users by means of iterative instances of classical one-time pad protocol. We show that our modular design may allow high-rate distribution of quantum conferencing keys among an arbitrary number of users and over arbitrary distances. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] Seminar Announcement: "CSP-CPV on a Single Thermo-Luminescent Crystal for a base load energy at record low costs- Prof. Carmel Rotschild (Technion), July 17, 12-1:30pm, Rm 5-314

by Catherine M Bourgeois

SPECIAL SEMINAR: TODAY! TODAY - Tuesday July 17 Room 5-314 1:30 pm CSP-CPV on a Single Thermo-Luminescent Crystal for a base load energy at record low costs by Carmel Rotschild, Visiting Professor, Technion The biggest challenge in solar energy today is not the electricity generation price, which is already under fossil fuel price for photovoltaics (PVs) (<0.04 $/kWh), but rather the ability to store utility-scale electricity at competitive prices. To date, the only method to efficiently and reliably store such energy is Thermal Energy Storage (TES) which is combined with Concentrated Solar Power (CSP). Despite its past decline, demands for CSP are increasing in that require alternative dispatchable energy generation. However, the combined production and storage price for this technology is still much higher than PVs (0.06 $/kWh - 0.12 $/kWh). Thermodynamically PVs and CSP relay on two different energy transport mechanisms. PVs relay on the free energy captured in an electron-hole pair generated by the quantum process of photon absorption, while CSP relay on the generation of many phonons in the process of thermalization, where free energy is lost. Even though these processes may be considered as independent, the generation of electron-hole pairs cannot occur spontaneously without the loss of free energy in a thermalization process. If PVs efficiency would tolerate high temperatures, for example, 600C, it would be beneficiary to concentrate solar radiation onto PVs, harvesting the available free energy, while in parallel harvesting the high-quality thermal energy through CSP. Doubling the conversion efficiency this way cannot be done with PVs as their efficiency decreases sharply with temperature, but can be done optically. In our method, we focus solar radiation onto a photoluminescence (PL) absorber and demonstrate 90% quantum efficiency while operating at 600C. The PL has a narrow line shape that matches the band-edge absorption of Si (or equivalent PV) and GaAs PVs, which offers CPV at 35% efficiency with minimal heating of the PV. The high quality heat at the PL-absorber is collected by heat transfer fluid (HTF) and converted to electricity at 35% turbine efficiency. A detailed analysis based on experimental validation of the concept shows 50% enhancement in the efficiency of CSP, with minimal additional costs thereby reducing expected electricity price own below 0.04 $/kWh.
