Hiii, I was curious and wondered if you use Marvelous designer when making clothes?

Hello, yes I use Marvelous designer to make clothes for the sims and then I use blender for the uv map and weights etc!

[jelliberri]

hii would you ever make cc for the sims 3?

Hello I’m actually not sure since I have never played the sims 3

[jelliberri]

hi! i dont know if this is the right place to ask but what ui overlay do you use? i am trying to find one like it and cant find it... if you dont mind me asking :)

hello! I’ve answered a similar question here 🤍

[jelliberri]

do u use reshade or gshade??

Hello! I use reshade. If you’re wondering which one; I used senshis reshade 4.0 I did tweak it a little more to my liking but for personal use.

[jelliberri]

your cc folder must so cute :c plss where u find your mods? or how can i dl your cc folder? >.<

I can’t put up my mods folder for download as that will go against a lot of cc creators’ Terms Of Use, but I do have a list of my favorite sims 4 creators 🤍

Hello,

I was wondering if your menu overrides and plumbob overrides were compatible with the newest update?

All my plumbobs are compatible with fairies! I’m not sure what you mean with my menu overrides, do you mean my pie menu overrides or main menu overrides?

If any of you have anymore questions related to my mods you can also always ask me in my community chat on Patreon!

Quantum State Tomography Cuts Three Qubit Measuring Needs

New Tomography Methods for Quantum State Description Cut Measurements and Improve Fidelity

QST

QST reconstructs an unknown quantum state from experimental observations, enabling quantum technologies to reach their full potential and ensure quantum instrument efficiency. Many quantum tasks require an accurate mathematical representation of the quantum state.

Conventional quantum state tomography is hindered by statistical noise, experimental errors, and the exponential increase in experimental demands and resource requirements as qubits increase. Full quantum state tomography is often needed to access nonlinear properties, even if other features may not require it.

The Breakthrough: Less Measurement, More Fidelity

Researchers improved quantum state tomography for three-qubit states by using a unique method that only requires 17 measurements, compared to the usual 63 Pauli measurements. In the challenging context of quantum computers, H. Talath, B. P. Govindaraja, and colleagues reported their achievement, which will ease the description of complex quantum systems.

The primary breakthrough is based on a theoretical prediction: a careful set of partial observations can explain most three-qubit pure states. Pure quantum systems have known states. This method contrasts with standard tomography, which requires many more observations to create the density matrix, a mathematical description of the quantum state.

Open-source quantum computing platform ibm_osaka achieved this reduced protocol with its 127-qubit processor. During experiments, they replicated a three-qubit W state and its two-qubit marginals. Its two-qubit subsystems consistently surpassed standard, full three-qubit tomography in W state fidelity, a measure of how closely the recreated state resembles the original. This confirms the theoretical benefit of recreating states from subsystems.

NISQ Device Benefits from Noisiness

Due to Noisy Intermediate-Scale Quantum (NISQ) device restrictions, this subsystem-based technique is practicable. NISQ devices, which have a finite number of qubits, are error-prone. Measurement numbers must be reduced to reduce error and improve result reliability. By focused on relevant subsystems, the unique approach allows for more frequent and deep analysis and more dependable and precise results, especially for noisy quantum systems.

Dealing with Noise with SIC-POVMs

Another quantum tomography study characterises three-qubit states with amplitude-damping noise and other environmental perturbations. This study emphasises the importance of correctly describing pure three-qubit states in these situations for information processing and quantum computing. Even with noise, generalised single-qubit Symmetric Informationally Complete Positive Operator-Valued Measures (SIC-POVMs) measurement probabilities can effectively identify the quantum state.

This section analyses the impact of amplitude-damping noise on the quantum state and measurement technique. Any qubit entangled with a noise-affected qubit is also affected by the noise. This shows how multi-qubit systems' qubits are connected and how it affects noisy state reconstruction.

In a noise-free scenario, only 10 of 64 possible outputs from SIC-POVM measurements can fully reconstruct a three-qubit pure quantum state and determine its unknown coefficients. This theory defines the relationship between measurement probabilities and noise characteristics to improve quantum state reconstruction in the presence of environmental disruptions.

Benefits and Challenges of SIC-POVMs

Since all tomographic data is in one experimental run, SIC-POVMs are conceptually advantageous. Quantum state tomography of neural networks has this advantage. Thus, when system size expands with Pauli tomography, it is empirically far more cost-effective to repeat the same measurement setup numerous times than to swap configurations exponentially.

Real-world applications are affected by this trait. Since each run includes complete tomographic information, the experimenter can end the method at any time, unlike other quantum state tomography-related systems that require at least one run per measurement setup to collect adequate information. Although SIC-POVMs have several benefits, they require consecutive measurements and precise settings, making them challenging to use.

Wider Effects

These advances in quantum state tomography speed up quantum technologies by lowering measurement counts and boosting noise resistance. They strengthen quantum information science theory and provide a framework for applying it in practice, contributing to the increasing quantum revolution. The findings support state reconstruction in noisy environments, which is essential for secure quantum communication protocols and fault-tolerant quantum computing. To improve the precision and applicability of quantum state tomography in real-world applications and the reliability of quantum mechanically based technology, this encourages additional research and creativity.

Hii! I was using your Message Bubble Pie Menu and noticed it’s not compatible with TwistedMexi’s Smarter Pie Menu v2.0. Any chance you could make them work together? Thanks in advance if you see this!

I'll have to check if its possible.
