DESCRIPTION:Tensor networks (TNs) offer powerful algorithms for simulating 
 quantum systems\, but struggle to represent states with high entanglement.
  In contrast\, quantum computers naturally accommodate entanglement\, thou
 gh developing efficient quantum algorithms remains an active area of resea
 rch. Integrating TNs with quantum computing has emerged as a promising str
 ategy to overcome limitations inherent to both classical and quantum appro
 aches. In this talk\, we will cover two examples of hybrid TN/quantum algo
 rithms. First\, we demonstrate how TNs can enhance the simulation of quant
 um dynamics on noisy quantum devices. In particular\, we use a TN algorith
 m to compress quantum circuits and show that this approach significantly r
 educes noise requirements to reach a practical advantage on noisy hardware
 . Second\, we explore how TNs can assist in preparing approximate ground s
 tates on quantum computers by optimizing parameterized quantum circuits. W
 e show that carefully selecting TN algorithms enables scaling to large qub
 it systems and that pre-optimizing circuits offers a promising strategy to
  avoid barren plateaus by providing warm-start initialization. Finally\, w
 e analyze the classical simulation costs of this approach and identify sce
 narios where quantum computers exhibit favorable scaling.\n\n\n\nhttps://c
