Kvantno računalništvo z nevtralnimi atomi v podjetju planqc

 

dr. Sebastian Blatt

planqc, Garching, Nemčija

 

 

Analogne kvantne simulatorje, ki temeljijo na ultrahladnih atomih ujetih v optične mreže, lahko uporabljamo za proučevanje sistemov kondenzirane snovi z ločljivostjo posameznega mesta v mreži. Težnje po vse boljšem nadzoru nad posameznimi atomi v takšnih sistemih so privedle do nove generacije eksperimentov, ki temeljijo na nizih atomov, sestavljenih z uporabo optičnih pincet. Takšne nize se lahko hitro oblikuje v različne geometrije v dveh in treh razsežnostih, atome v njih pa je mogoče preplesti s pomočjo Rydbergovih interakcij dolgega dosega. Na podlagi teh dosežkov so se nizi atomov uveljavili kot ena najobetavnejših platform za gradnjo digitalnih kvantnih računalnikov, saj (1) atomi omogočajo realizacijo kubitov s koherenčnim časom, dolgim več sekund, (2) med posameznimi atomi ni razlik in (3) je nize atomov mogoče enostavno razširiti do velikosti nekaj tisoč kubitov. Predstavil bom prototipe digitalnih kvantnih računalnikov, razvite v okviru akademskih projektov pobude Munich Quantum Valley, in komercialne kvantne računalnike, ki jih razvija podjetje planqc.

 

O predavatelju: Sebastian Blatt je soustanovitelj in tehnični direktor podjetja planqc. Pred tem je vodil raziskovalne skupine na Univerzi Ludwiga Maximiliana v Münchnu in na Inštitutu Maxa Plancka za kvantno optiko. Posveča se razvoju skalabilnih kvantnih računalnikov v okviru podjetja planqc in pobude Munich Quantum Valley.

Quantum Computing with neutral atoms at planqc

 

Dr. Sebastian Blatt

planqc, Garching, Germany

 

 

Analog quantum simulators based on ultracold atoms trapped in optical lattices can be used to study condensed-matter systems with single-site resolution. The quest for more control over individual atoms in such systems has culminated in a new generation of experiments based on atom arrays assembled using optical tweezers. These atom arrays can be created rapidly in arbitrary two- and three-dimensional geometries, and atoms in these arrays can be entangled using long-range Rydberg interactions. Based on these developments, atom arrays have emerged as one of the most promising platforms for building digital quantum computers because (1) atoms can realize qubits with coherence times of many seconds, (2) they exhibit no manufacturing variations, and (3) it is straightforward to scale up to arrays with thousands of qubits. I will present the digital quantum computer demonstrators developed in the academic projects within Munich Quantum Valley, as well as the commercial quantum computers developed at planqc.

 

About the lecturer: Sebastian Blatt is the co-founder and Chief Technology Officer of planqc. Prior to that, he led research groups at Ludwig Maximilian University of Munich and the Max Planck Institute of Quantum Optics. He is currently focused on the development of scalable quantum computers within planqc and the Munich Quantum Valley initiative.
