This places an upper bound on the lifetime of quantum information stored in them. We address this issue for a topological subsystem code introduced in [Bravyi S.{\\em et al.}, Quant.~Inf.~Comp.~13(11):0963]. By frequently measuring the gauge operators of the code, a technique known as Operator Quantum Zeno Effect [Li Y. {\\em et al.}, preprint arXiv:1305.2464], the dynamics responsible for quasiparticle motion is suppressed, and can eventually be ``frozen\" in the large frequency limit. A feature of this method is that the density operator of the code does not commute with the measurement operators, so the density matrix will be randomised after a few measurements. However the logical operators commute with the measurement operators and are thus protected.<\/jats:p>","DOI":"10.26421\/qic14.13-14-6","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T00:18:09Z","timestamp":1614557889000},"page":"1136-1148","source":"Crossref","is-referenced-by-count":1,"title":["Quasiparticle localisation via frequent measurements"],"prefix":"10.26421","volume":"14","author":[{"given":"David A.","family":"Herrera-Marti","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leong Chuan","family":"Kwek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10955","published-online":{"date-parts":[[2014,10]]},"container-title":["Quantum Information and Computation"],"original-title":[],"deposited":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T00:18:17Z","timestamp":1614557897000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.rintonpress.com\/journals\/doi\/QIC14.13-14-6.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,10]]},"references-count":0,"journal-issue":{"issue":"13&14","published-online":{"date-parts":[[2014,10]]},"published-print":{"date-parts":[[2014,10]]}},"URL":"https:\/\/doi.org\/10.26421\/qic14.13-14-6","relation":{},"ISSN":["1533-7146","1533-7146"],"issn-type":[{"value":"1533-7146","type":"print"},{"value":"1533-7146","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,10]]}}}
