quantumcomputing/32894_c65187f488c01dde_1106.txt | By enabling agents to communicate, recent cooperative multi-agent reinforcement learning (MARL) methods have demonstrated better task performance and more coordinated behavior. Most existing approaches facilitate inter-agent communication by allowing agents to send messages to each other through free communication chan... |
quantumcomputing/78a519dd_121904.txt | In addition to being â robust,â MAD and MAE also preserve scale, unlike the formal likelihood-based approach discussed next. Unless combined with a transformation, scale-preserving error metrics have the same units as the data, such that their magnitude roughly corresponds to the magnitude of the typical error. Whil... |
quantumcomputing/4628_578753610752009e_100.txt | The qubits are now delivered to Bob. If Bob somehow knew Alice’s basis string, then it would be possible for him to determine the parent string as well. He would simply measure Z or X on the qubit, as appropriate. But Bob does not know the basis string. So instead, he just makes up his own random basis string of Zs and... |
quantumcomputing/1629_3abeac199875c936_620.txt | • Overcoming operational epistemology (consisting in interactionism plus instrumentalism), we need to enlarge the concept of operation. In particular, preparation can be seen as determinative measurement, while premeasurement as an interrogation of a system relative to a degree of freedom. Finally, detection is an answ... |
quantumcomputing/3960_96169d905c875778_2.txt | I went home and immediately started researching TMS and Neurostar so I could better understand the treatment and then talk to my wife about it. The first thing I found was a newly opened TMS clinic on the other side of town. That was one hurdle down. Next, I found quite a bit of information on the procedure itself, all... |

quantumcomputing/22087_db9c0f2f4b6f960d_1760.txt | This work lays the foundations of the theory of kinematic changeable sets ("abstract kinematics"). Theory of kinematic changeable sets is based on the theory of changeable sets. From an intuitive point of view, changeable sets are sets of objects which, unlike elements of ordinary (static) sets, may be in the process o... |
quantumcomputing/16776_5e68663f418490bf_197.txt | Non-linear dynamical systems can be handily described by the associated Koopman operator, whose action evolves every observable of the system forward in time. Learning the Koopman operator and its spectral decomposition from data is enabled by a number of algorithms. In this work we present for the first time non-asymp... |

quantumcomputing/14816_baea7bc0d09df8ad_105.txt | Independent researcher Daniel Boyd presents Emergent Information Theory (EIT) to bridge the mind-body gap by considering biological and technological information systems as a possible mechanism of “non-material mind” (as defined in an informational context) influencing the physical body. EIT uses the term “information”... |
quantumcomputing/22087_723fd0fbfe5d7a11_251.txt | In this paper, we propose a generic quantum circuit resynthesis approach for compilation. We use an intermediate representation consisting of Paulistrings over {Z, I} and {X, I} called a ``mixed ZX-phase polynomial``. From this universal representation, we generate a completely new circuit such that all multi-qubit gat... |
quantumcomputing/3470461d_6862.txt | Large language models (LLMs) are increasingly adopted for a variety of tasks with implicit graphical structures, such as planning in robotics, multi-hop question answering or knowledge probing, structured commonsense reasoning, and more. While LLMs have advanced the state-of-the-art on these tasks with structure implic... |
quantumcomputing/3591cd7e_11653.txt | Read the questions below, think about your answers, then click the triangles to reveal the solutions. Encode the data vector x⃗=(0,π/4,π/2)\vec{x} = (0, \pi/4, \pi/2)x=(0,π/4,π/2) using angle encoding, as described above. Using angle encoding as described above, how many qubits are required to encode 5 features? |
quantumcomputing/175_40094682244c3a83_1709.txt | Despite the tremendous success of reinforcement learning (RL) with function approximation, efficient exploration remains a significant challenge, both practically and theoretically. In particular, existing theoretically grounded RL algorithms based on upper confidence bounds (UCBs), such as optimistic least-squares val... |
quantumcomputing/8337_9bb65989695b7ff4_228.txt | ***Weak quantum measurement*** (Aharonov et al. 1988) is a process where a quantum wave function is not irreversibly collapsed by absorbing the particle but a small deformation is made in the wave function whose effects become apparent later when the particle is eventually absorbed in a 'post-selection' e.g. on a photo... |
quantumcomputing/883f941c_117750.txt | In 2023, Microsoft Quantum researchers published a paper in Physical Review that described a new device that can represent a logical qubit with hardware stability, measuring a phase of matter consistent with the observation of topological superconductivity and Majorana zero modes. The scientists reported that such dev... |
quantumcomputing/e52c6b6a_115733.txt | Similar to what we did with the (Z ) gate, we can follow the same procedure for any other gate, like for example, parametrized gates such as a the controlled versions of (RX( theta), RY( theta), RZ( varphi) ) , or the controlled phase gate (CP( varphi) ) : |
quantumcomputing/3960_0678c516274774e4_35.txt | I’m not just saying that; I really mean it. You claim you can’t understand a word I write, but for me it’s the other way around. I’ve already tried repeatedly to tell you, your ditto-heads, and other commentators in plain English that my essay nowhere relies on naïve set theory, and in fact can be construed as a condem... |
