Holstein Primakoff spin codes for local and collective noise
Sivaprasad Omanakuttan, Tyler Thurtell, Andrew K. Forbes +2
Quantum error correction is essential for fault-tolerant quantum computation, yet most existing codes rely on local control and stabilizer measurements that are difficult to implem…
Logical channels in approximate Gottesman-Kitaev-Preskill error correction
Mahnaz Jafarzadeh, Jonathan Conrad, Rafael N. Alexander +1
The GKP encoding is a top contender among bosonic codes for fault-tolerant quantum computation. Analysis of the GKP code is complicated by the fact that finite-energy code states l…
Logical channel for heralded and pure loss with the Gottesman-Kitaev-Preskill code
Tom B. Harris, Takaya Matsuura, Ben Q. Baragiola +1
Photon loss is the dominant source of noise in optical quantum systems. The Gottesman-Kitaev-Preskill (GKP) bosonic code provides significant protection; however, even low levels o…
Quantum-Enhanced Multi-Parameter Sensing in a Single Mode
Christophe H. Valahu, Matthew P. Stafford, Zixin Huang +7
Precision metrology underpins scientific and technological advancements. Quantum metrology offers a pathway to surpass classical sensing limits by leveraging quantum states and mea…
Linear-optical quantum computation with arbitrary error-correcting codes
Blayney W. Walshe, Ben Q. Baragiola, Hugo Ferretti +11
High-rate quantum error correcting codes mitigate the imposing scale of fault-tolerant quantum computers but require efficient generation of non-local, many-body entanglement. We p…
The Quantum Internet (Technical Version)
Peter P. Rohde, Zixin Huang, Yingkai Ouyang +14
Following the emergence of quantum computing, the subsequent quantum revolution will be that of interconnecting individual quantum computers at global level. In the same way that c…
