Computational problems, Yes, the Solution of computational problems, that can never be solved in a feasible time period by the existing supercomputers is the basic need of a Quantum computer. Quantum Computers use quantum-mechanical phenomena like Superposition and Entanglement to perform computation. Superposition refers to the presence of a quantum particle like an atom or a photon in two states simultaneously, exactly it is not simultaneous but it spins so quickly that it appears to be in both positions at the same time. Entanglement is a physical phenomenon in which a group of quantum particles, interact, share spatial proximity in such a way that their quantum states remain dependent on one other even if they get separated by larger distance. Such particles show wave-like properties, and when frequency and waveform of these particles become identical, they are said to be in Coherence. Coherence is a mandatory condition to perform computing. In a Quantum System, Superposi...
What are Third-party apps?
Third-party apps are apps developed by someone other than your phone manufacturer( Apple, Nokia, Motorola...) or Operating system provider(Android, iOS...).

| Third-party Apps |
Such apps are often downloaded by us to get any specific task done but they can be a threat to the security of our phones and even to our bank accounts.
Because these apps always ask us to grant permissions like using Storage, Contacts, Microphone, Location, etc.
Using these permissions they can easily access our private information such as passwords, user IDs, documents, media files, etc.
How third-party apps are dangerous to our phone's security?
These apps are often embedded (attached from inside) with an unidentifiable or hidden piece of codes or scripts.

| Malware Scripts |
Usually, our phones don't come up with a preinstalled firewall that's why such codes are not usually detectable by the operating system.
Once we install such vulnerable (suspicious) apps and grant permission to use our phone's resources we give them access to do whatever they want to do with our private data and connected devices.
Types of embedded vulnerable scripts
Madwares
Often get installed without our consent and collects data of our likes and dislikes to suggest to us relevant advertisements by companies but can also be used for password predictions.
Spywares
Spywares collect data of our searches, contacts, and locations visited and send this information to be analyzed.
Viruses
They are often found attached with genuine-looking apps to extract important information stored in our devices such as banking user ID or passwords.
Trojans
Trojans are often attached to the back end of such apps to mine confidential information and attack our device.
Graywares
Not completely malicious but leak information partially
Phishing Apps
Apps that pretend to be genuine and make ourselves to enter important information.
Drive-by Downloads
Whenever we download something they get downloaded and lead us to some malicious link.
Security measures to avoid Cyberattacks
Install applications with an editor's choice mark (like Google's Playstore or iOS Store) to download apps.
Don't download apk files from untrusted websites.
Don't grant permissions to the irrelevant interest of your phone's resources (like keyboards usually don't require storage or contact permissions).
Always keep "Installation from unknown sources" disabled.
Don't accept cookies from untrusted websites.
Don't use free antiviruses or firewalls as they could be potentially harmful instead of providing security.
Don't save private information like passwords or usernames of your bank account access in your browser.
While accessing your banking services always use a virtual keyboard.
Instantly clear your cache and cookies from untrusted websites.
Nowadays many companies use 25% of app development's duration on testing so they could target you to test their apps.
If it gets very important to download a 3rd-party app, please conduct at least one Google search to check whether it has negative reviews, if it is there then it is better to avoid the download.
Never share OTPs.
Today our phone has become our identity and also a key to unlock our bank accounts, So keep them at the safest place.
