==Qubit storage==
In 2008 a team of scientists from the U.K. and U.S. reported the first relatively long (1.75 seconds) and coherent transfer of a superposition state in an electron spin "processing" qubit to a [[nuclear spin]] "memory" qubit.<ref>{{cite journal |author=Morton |first=J.

In 2013, a modification of similar systems (using charged rather than neutral donors) has dramatically extended this time, to 3 hours at very low temperatures and 39 minutes at room temperature.<ref>{{cite journal |author=Kamyar Saeedi |year=2013|title=Room-Temperature Quantum Bit Storage Exceeding 39 Minutes Using Ionized Donors in Silicon-28|volume=342|pages=830–833|doi=10.1126/science.1239584|issue=6160|journal=[[Science (journal)|Science]]|bibcode = 2013Sci...342..830S |display-authors=etal |pmid=24233718|arxiv=2303.17734 |s2cid=42906250}}</ref> Room temperature preparation of a qubit based on electron spins instead of nuclear spin was also demonstrated by a team of scientists from Switzerland and Australia.<ref>{{cite journal|last1=Náfrádi|first1=Bálint|last2=Choucair|first2=Mohammad|last3=Dinse|first3=Klaus-Pete|last4=Forró|first4=László|title=Room temperature manipulation of long lifetime spins in metallic-like carbon nanospheres|journal=Nature Communications|date=July 18, 2016|volume=7|page=12232|doi=10.1038/ncomms12232|pmid=27426851|pmc=4960311|arxiv=1611.07690|bibcode=2016NatCo...712232N}}</ref> An increased coherence of qubits is being explored by researchers who are testing the limitations of a [[Germanium|Ge]] [[Electron hole|hole]] spin-orbit qubit structure.<ref>{{Cite journal|first1=Zhanning |last1=Wang |first2=Elizabeth |last2=Marcellina |first3=A.
