STA, 9 May 2018 - Researchers of the Jožef Stefan Institute (IJS) have confirmed four-decade old presumptions of Nobel Prize laureate Frank Wilczek of the existence of particles other than fermions and bosons. Their achievement is seen as an important step towards the creation of a topological quantum computer. 

A group of Slovenian physicists together with their Swiss counterparts has confirmed the existence of two kinds of atypical anyon quasiparticles in a special kind of quantum magnet, Ruthenium(III) chloride.

The news of the scientific breakthrough was reported by the prestigious scientific journal Nature Physics.

Since anyons are very stable particles, the discovery of the Slovenian physicists is seen as an important step towards the creation of a topological quantum computer, which the IJS says is the Holy Grail of the technology of the future.

According to the head of the research team for solid-state physics at the institute, Martin Klanjšek, Microsoft is already working to create such a computer but based on a different kind of anyons which unlike those discovered by IJS researchers are difficult to access.

"We wish this article makes Ruthenium(III) chloride a real alternative for the basis of the topological quantum computer," Klanjšek told the STA.

Wilczek thought about particles other than fermions and bosons four decades ago. He named them anyons.

The new particles can be found in nature as free particles and in substance as quasiparticles.

Russian-American physicist Alexei Kitaev wrote in a highly cited article in 2006 that anyon quasiparticles could exist in a special type of a bilayer quantum magnet with a hexagonal lattice.

A few such quantum magnets were successfully created only in recent years. Physicists around the world thoroughly studied the most promising among them, the Ruthenium(III) chloride, for the last three years to either confirm or deny the existence of anyons.

Klanjšek said the race, which the Slovenian team entered a year ago, was tough. The IJS team succeeded, because it managed to interpret its results in a new, unconventional way, the institute said.

Now that the existence of these extraordinary particles has been confirmed, Klanjšek expects scientists to be busy finding ways to manipulate them for the next decade.

Slovenia Traffic Info

  • The first significant increase in foreign vehicles driving on Slovenian roads before the main summer tourist season is during the Easter holidays.

    We are therefore expecting increased traffic at the end of this week from Austria and Italy in the direction of the border crossings with Croatia and from Italy to Hungary.

    Holidays in certain parts of Europe start on Thursday, 29 March; therefore, we may expect increased traffic from Austria in the direction of Croatia. On Thursday, we also expect heavy freight traffic and long waiting lines at the border crossings with Croatia.
     

    Roads will be heavily burdened on Friday, 30 March. Heavy congestions can be expected on the Lower Carniola motorway at Dobruška vas due to construction works.
     

    Due to the end of the holidays in most European countries, traffic will be significantly increased in the opposite direction on Monday, 2 April, and Tuesday, 3 April. 


    The electronic tolling system is being implemented on 1 April and short road closures are to be expected during the night.

    When and where there will be the most traffic based on data from previous years: info.


    You can view the travel times on certain sections live on the website of the Traffic Information Centre at www.promet.si.

    Limitations for freight traffic

    Please note that limitations for freight traffic in Slovenia also apply on Easter Friday and later on Sunday and Monday. There will be no limitations in Slovenia on Saturday.

    You can view limitations in Slovenia and in neighbouring countries here.

    Expected construction works and road closures


    A2, Ljubljana - Obrežje

    A full road closure is expected in the Dobruška vas - Drnovo section until 21 May, which will be carried out in five stages. Traffic shall run on the other half of the motorway in both directions. Due to the full closure of the section, the Smednik junction will host temporary passage. Due to the closure of junction sections A and B at the Smednik junction (the expected start of the construction works is at the beginning of April), a detour will run on state-owned roads. The Zaloke jug rest area will be closed for the duration of the closure.

    A2, Ljubljana - Karavanke

    From Monday, 16 April to Thursday, 19 April from 8am to 4pm there will be maintenance works in the Karavanke tunnel.
    Traffic will run at intervals with waiting times at each end of the tunnel of up to 30 minutes. The maximum transport width is 3.5m.   à

    A1. Ljubljana - Koper, H4, Vipavska dolina

    As part of adjusting the toll booths for the DarsGo system, there will be a full half hour closure of the Divača - Kozina section on Monday, 2 April between 12am and 1am due to the removal of the signalisation at the CP Videž gantry. There will be a short closure of the Gabrk - Sežana vzhod section on Tuesday, 3 April between 4am and 6am due to the removal of the signalisation at the CP Dane gantry. Traffic will also occasionally be hindered outside the listed dates.

    Within the next phase of a more extensive renovation of the Vipava expressway, the worn roads in certain sections of the Vipava-Ajdovščina and Ajdovščina-Selo expressway in the total length of 7.7km will be renewed in each direction. The contractor will begin the renovation works as soon as the weather allows for it or after the end of the winter service on the motorways and expressways at the latest, most probably in the last third of March.

    A1 Maribor - Ljubljana, A5 Maribor - Lendava

    On the night of 1 April, traffic will be hindered at toll booths on the A1 at CP Vransko, CP Kompolje and CP Pesnica, on the A5 at CP Dragotinci, and on the A4 at CP Prepolje due to the implementation of the new traffic signalisation. CP Vransko will also have a half hour full closure in both directions at around midnight.

    Due to road patching works, traffic will be hindered at CP Vransko on Saturday, 31 March. 

    From Tuesday, 3 April to Saturday, 7 April, road patching works will commence on the A5 motorway at Vučja vas, Murska Sobota.
    On Saturday, 7 April, lines will be painted for the toll booths on the Styria motorway, while road patching works at CP Tepanje will commence on Sunday, 8 April.

    Prevention

    We are already seeing bikers on our roads and numerous national prevention initiatives to increase the safety of bikers are already taking place. The purpose of the initiatives is to make bikers aware of the importance of preparing appropriately at the start of the biker season, of wearing protective gear, of unexpected situations on the roads and of other participants in road traffic. More can be found at the link bikers.

    Speed as a risk factor remains one of the main reasons for traffic accidents and is an important contributor to the severity of consequences and the number of people severely or mortally injured in these accidents. Therefore we urge you to be attentive and to adjust your speed to the conditions on the road!

    Traffic information

    We suggest that you check the status of the roads using:
    - the website www.promet.si,
    - the PIC operator by dialling 1970 (the number is not free of charge) or the responder 080 22 44 (free of charge),
    - the mobile application DarsPromet+,
    - the social media (Twitter @promet_si and www.facebook.com/Vozimo.pametno),
    - the traffic information on radio stations.

    The Traffic Information Centre for Public Roadswishes you a pleasant and prudent drive.
